Your Relationship Horoscope Book, created personally for you two

A Relationship Horoscope Book (technically known as synastry) overlays your two birth charts and shows how the planets of one person interact with those of the other: where you understand each other effortlessly, where there is chemistry, where friction arises, and where your greatest areas of growth as a couple lie. At KosmosGenie, you receive this not as a short summary but as a personal book, chapter by chapter, with both of you given equal weight.

Here's how precise it is: Both birth charts and their connections are calculated with astronomical accuracy, the same foundation that experienced astrologers work with. From this, a cohesive interpretation is created without generic templates. Every factual detail is automatically checked against the calculation before delivery. Anything that does not pass the check is rewritten.

What you need: the birth date and birthplace of both people, and, if possible, the birth time. The birth time makes the interpretation more precise because it determines the Ascendant and the houses. It is not required, however. All chapters are created even without a birth time.

★★★★★Silvia S.✓ Verified purchaseOctober 2026

Some passages are funny, others surprisingly honest, and a few really touched me. I especially loved the beautiful description of what we can give each other. I’ll definitely keep the Relationship Horoscope Book, and I recommend it to everyone.

★★★★★Chris✓ Verified purchaseOctober 2026

It has everything you could want. Very accurate and even helpful. Highly recommended.

★★★★★Stefan✓ Verified purchaseOctober 2026

Horoscopes aren’t really my thing, but my wife was absolutely thrilled with her birthday gift.

★★★★★Yvonne✓ Verified purchaseOctober 2026

Some of it is absurdly spot-on, almost eerily accurate.

★★★★★Kristin✓ Verified purchaseOctober 2026

I gave my husband the Relationship Horoscope Book for our anniversary. At first, he laughed a little, but that evening we ended up sitting down and reading it together. Such a lovely idea for couples who feel like they already know everything about each other. Would definitely recommend it.

★★★★★H.M.✓ Verified purchaseOctober 2026

Lovely! There was a small mistake in my Relationship Horoscope Book, but before I even noticed it myself, a corrected book had already been sent to me. Great service and very friendly. The book is wonderful.

My husband and I love it :-). Beautifully written and spot on. A lovely book

★★★★★Tina✓ Verified purchaseSeptember 2026

Very detailed and lovingly presented with openness. It helped me a lot and explained quite a few things, too. The price is more than fair. I highly recommend it!

FAQ: Common Questions About the Relationship Horoscope Book

What is a Relationship Horoscope Book?

A Relationship Horoscope Book (technically known as synastry) compares your two birth charts with each other. It shows how your Suns, Moons, Venus and Mars placements, and all the other planets relate to one another: where you understand each other effortlessly, where tension naturally arises, and where shared growth is waiting.

What details do I need for a Relationship Horoscope Book?

For each person: date of birth and place of birth, and ideally the time of birth as well. The birth time makes the interpretation more precise, because it determines the Ascendant and the houses. It is not essential, though.

Do we both need birth times for a Relationship Horoscope Book?

No. Even without a birth time, you get a meaningful Relationship Horoscope Book with all chapters included. The planetary positions and their connections remain valid. Adding birth times brings in the Ascendant and the houses, which adds depth rather than extra pages. Simply leave the time field blank if you don't know the birth time.

Does the Relationship Horoscope Book tell us whether we are compatible?

It does not rate your relationship as “compatible” or “not compatible”, and it does not predict the future. It gives you an honest look at where your strengths as a couple lie and where friction is natural, as an invitation to understand each other better. A mirror for shared reflection, not a forecast.

Is a Relationship Horoscope Book only for romantic couples?

No. A Relationship Horoscope Book suits any close connection: romantic, friendship, family, or business partnership. It describes the dynamic between two people, regardless of the nature of the relationship.

How quickly will the Relationship Horoscope Book arrive?

The digital book (ePub, PDF) is delivered by email and available in your account within approximately 5 hours of payment. The printed book is made to order: allow approximately 7–10 business days to Germany, or approximately 2–3 weeks to all other countries, including printing and shipping. If it ever takes longer, we will get in touch by email.

What is the difference between the Book and Premium editions of the Relationship Horoscope Book?

Both are printed A5 books with a personalized starry-sky cover, and the digital edition is included with each. Book = softcover. Premium = hardcover with a sewn binding, printed on premium paper, with a dedicated dedication page for your own words.

Is a Relationship Horoscope Book a good gift?

Absolutely. Simply enter both people's birth details. In the Premium edition especially, with its hardcover, premium paper, and personal dedication page, it makes an exceptional gift: for an anniversary, an engagement, a wedding, or Valentine's Day. If you don't know the details, a gift voucher is the perfect solution.

Can we exchange or cancel the Relationship Horoscope Book?

Because your copy is calculated and written individually for you, the statutory right of withdrawal for personalized goods does not apply (§ 312g para. 2 no. 1 of the German Civil Code). You expressly agree to this during the ordering process. We will of course replace any damaged or misprinted books. See the “Returns” page for details.

What happens to your birth data when you order a Relationship Horoscope Book?

The data for both people is used solely to create your Relationship Horoscope Book and is treated confidentially. You can find more information in our Privacy Policy.

Where can I get a Relationship Horoscope Book?

You can order a Relationship Horoscope Book directly here from KosmosGenie, with no appointment needed. You’ll need the birth date and birthplace of both people. The birth time makes it more precise, but isn’t required. Then choose your format and pay securely. The digital book (ePub, PDF) will arrive by email within about 5 hours of payment. The printed book takes about 7–10 business days to arrive in Germany, and about 2–3 weeks to arrive in all other countries.

How much does a Relationship Horoscope Book cost?

The Relationship Horoscope Book comes in three formats: Digital €12.90, Book €51.90, and Premium €71.90. The digital edition is included with every printed book, and worldwide shipping is included. All prices include VAT.

Can I buy or order the Relationship Horoscope Book as a printed book?

Yes. The Relationship Horoscope Book is available as a printed softcover book and as a Premium hardcover with a dedication page. Every copy is printed individually for you, and you order it directly on this page. Worldwide shipping is included: approximately 7–10 business days to Germany, or approximately 2–3 weeks to all other countries.

Is a Relationship Horoscope Book from KosmosGenie trustworthy?

“Is getting a relationship horoscope done worth it?” is a common question, and the honest answer is this: the planetary positions, houses, and aspects are calculated with astronomical precision from the birth data, using the same foundation that professional astrologers work with. Every statement in the book is automatically checked against this calculation before delivery, and you can view a complete sample book before you buy. Behind KosmosGenie is Butterflies IT UG (haftungsbeschränkt), based in Schwerin, with a published imprint, an invoice showing VAT, and independently verified reviews on ProvenExpert. We do not promise what no one can deliver. A Relationship Horoscope Book is a detailed, personal interpretation for self-reflection, not a prediction.

Is the Relationship Horoscope Book also called a partnership horoscope or couple's horoscope?

Yes, they all refer to the same thing. Partnership horoscope, couple's horoscope, relationship horoscope, synastry horoscope, and horoscope for couples all describe the comparison of two birth charts. At KosmosGenie, you receive this as a personal book, digital or printed.

Buying a Relationship Horoscope Book, ordering one, or having one created: what is the difference?

Neither, it’s the same path. You order the Relationship Horoscope Book here, and it’s calculated and written especially for you. People search for it in many ways, for example, “relationship horoscope book,” “get a relationship horoscope interpretation,” “get a partnership horoscope created,” “buy a partnership horoscope,” “get a synastry chart created,” “get a synastry horoscope created,” “synastry interpretation,” “get a relationship horoscope created,” “get a couple’s horoscope created,” “get a horoscope for couples created,” “get a personal relationship horoscope created,” “individual relationship horoscope,” “detailed relationship horoscope,” “relationship horoscope with birth time,” or “relationship horoscope book as a gift.” They’re all looking for the same thing: a personal Relationship Horoscope Book, in digital or printed form.

Is the Relationship Horoscope Book a good gift for an anniversary, an engagement, a wedding, or a couple?

Yes, a Relationship Horoscope Book makes a very personal gift for an anniversary, an engagement, a wedding, or a couple. Simply enter the birth data of the people you are gifting it to, and in the Premium format with a hardcover and dedication page it becomes a book they will keep. If you do not know the birth data, the KosmosGenie gift voucher is the perfect solution. It is redeemed with the real data.
