Review—The 13th Sign
Ophiuchus and the Astrology They Don’t Want You to See
By Niki Tennesen | niki@siderealinternational.org

Sidereal Astrology has been the subject of many debates, but none more often than now as the world awakens to the realization that astrology in the mainstream doesn’t use the real sky! As technology has become more advanced, it’s given the world an opportunity to look at the stars in a way that hasn’t been for so long. The word is out, and many of us will never go back to the traditional astrology we once relied on for guidance.
Dr. Dani Inman challenges that tradition with her new book The 13th Sign: Ophiuchus and the Astrology They Don’t Want You to See. The first part of this book details astrology’s esoteric and scientific connections, what it means to live cosmically aligned, speaks to our collective experience of shifting realities, and how important the recognition of constellation Ophiuchus is as we reclaim the true sky paradigm. Dani doesn’t hold back on her thoughts and feelings of how Ophiuchus has been the missing piece on our cosmic journey this whole time.

Dani doesn’t hold back on her thoughts and feelings of how Ophiuchus has been the missing piece on our cosmic journey this whole time.
Dr. Dani Inman is one of the many incredible souls that has awakened to True Sidereal Astrology and has made it her mission to be the light in our growing and evolving sidereal community. Her love for human life and fascination with its natural cycles within cycles has led her on a cosmic journey of her own, studying and questioning so that she can share how to interpret the incredible cosmic blueprint gifted to us at birth. Not only does she deliver star-seeds, she’s sharing her knowledge of the stars to guide them along their journey here on earth.
Her book is an incredibly detailed; a comprehensive guide for any level of astrologer wanting to integrate Ophiuchus into their healing practice. Not only has Dani gone into great detail about this particular constellation, she includes the meaning of each planet and lunar nodes in Ophiuchus as well, making it an easy go-to reference guide for astrologers of all levels. Recognizing Ophiuchus as an active constellation in our zodiacal belt is an astronomically grounded perspective, and Dr. Dani has proven she’s well-experienced in this book.
What do the stars of Ophiuchus mean? How do planetary energies play in that constellation? To some of us, Ophiuchus is quite normal to include in our charts and readings. To other disciplines of astrology, he goes unrecognized. Her book shows us how important it is to actualize the power found in Ophiuchus, as she describes it to be the archetype of the Magician-Alchemist, the one who understands the laws of reality and transcends them. She brings the energy of the serpent bearer to life.
“Ophiuchus represents the process of refining spiritual lead into divine sovereignty. It carries awareness…integrating it, using every challenge as raw material for wisdom, power, and ascension.”

Dr. Dani really does encapsulate beautifully the meaning of each planet and lunar node in Ophiuchus in her detailed descriptions. The other 12 constellations are organized and detailed for you quite differently than you would expect in the second half of her book. The Cosmic Healer’s Journey isn’t the traditional Aries-Pisces story that starts with a call for action, and ends with the hero returning home, just to repeat it again and again. In fact, it’s quite the opposite as she takes us through the meaning of each constellation of the zodiac clockwise, calling it the path of final transcendence.
She states it’s not a story of return, but of completion. It is a journey of the soul that already knows it’s here to complete its mission—one that doesn’t start with birth, but with death in the stars of Scorpio. Each constellation speaks to the journey that the soul is undertaking, from choosing to incarnate, soul programming, like family and culture, becoming an individual and breaking through the illusions to find our way home, and setting out to connect with our tribe. Our last step in the cosmic healer’s journey ends in Ophiuchus with ascension; not a repeat, but finally conquering the cosmic wheel.
Dani takes a unique and esoteric approach in this book that I appreciate because she truly understands the raw science of astrology and astronomy, yet is quite able to communicate her own connection with the stars and divinity in her interpretations. Dani has woven significant star wisdom and valuable insight into her book, making it truly one that every practicing constellational astrologer needs for their shelf.
In illuminating the often-overlooked role of Ophiuchus, I have to say that Dr. Dani’s contribution stands as a meaningful addition to the evolving body of astrological studies. I also believe that it will open the door for others, influencing a deeper look into the dynamic relationship between astronomy and astrological tradition.

Dr Dani is an incredible heart led teacher. As a student in her Stellar Foundations astrology course, she really leads from a place of passion.
I’m so glad that Dr Dani wrote this book!
A great resource for those learning what the stars say about a soul’s path or those learning how to become an Astrologer.
I highly recommend her book and her astrology course
Wow! This is so exciting! The idea of the 13th sign has been on my mind for years, but like anything new, it’s difficult to understand how the energy can be implemented and understood in one’s everyday reality. Thank you for sharing the highlights 🙂
