I received a free copy of this book in exchange for a fair and honest review. All opinions are my own. 

A group of heroes makes their final journey into the underworld to find and save a young girl who may hold the key to unlocking the mysteries of the stars in author Kim Idynnes’ “The Secret of Ophiuchus”, the third book in the Enigma series. 

The Synopsis

In the final installment of the Enigma series, Surina and Dominic descend into the tunnels of Wupatki to rescue Hannah Hale. Their plans are tripped up by an unexpected tagalong, and Surina is uneasy about Hannah’s sympathy for Tagua, a demon sorcerer of the underworld. Hannah assures them that they can return home if they set things right in the zodiac and learn the secret of Ophiuchus—but is she willing to return alone, or will she unwittingly release Tagua into their world?

The Review

This was a brilliant end to the Enigma trilogy. The author does such a great job of building upon the character-driven narratives and world-building established in the first two books, while also bringing in new perspectives and shifting evolutions for the characters themselves. The way the author can mesh together elements of multiple mythologies and belief systems, including Greek and Sumerian mythology, was inspired and so creatively done that it felt seamless and effortless on the page. 

The imagery in the book was so cosmic and did an excellent job of showcasing the stakes of the mission Hannah and her allies find themselves on. The twists that come with Hannah and Tagua throughout the story bring into the narrative an essential theme of exploring what happens when the heroes of old legends or history itself are revealed to have caused equal or even more damage in their wake, with perspective playing an integral role in the stories we tell one another and ourselves in the end.

The Verdict

Memorable, epic, and compelling, author Kim Idynne’s “The Secret of Ophiuchus” is a must-read fantasy-driven novel and a great end to the Enigma series. The twists and turns in the narrative, the rich character development, and shocking moments that will leave readers wanting more will stay with them long after the final page ends.
