Ancient magic. Secret societies. A thirst for vengeance.
Welcome to The Grigori Cycle, a multi award-winning supernatural thriller series by Jes Honard and Marie Parks, brought to life by the audiobook narration talents of the acclaimed Mary Robinette Kowal.
In 2024, you helped us create the audiobook of Unrelenting, the first book in The Grigori Cycle, through a successful BackerKit campaign. The novel follows Bridget's desperate search for her missing sister, leading her to discover a sinister secret and powerful magic.
Now, we're welcoming you back into the story for the second installment. In Undeniable, Bridget must come to terms with the irreparable impact of the supernatural world of the Grigori on her life, while seeking to resurrect a murdered friend. However, the magic that would save them paints a target on her back.
Mary Robinette Kowal has said "yes!" to recording Unrelenting. The book is complete. The audio engineer is in place.
All that's left is to give you early access as the backers who will make this project possible!
High-quality audiobooks are complex projects that require a significant investment and considerable talent.
We refuse to let AI touch any part of the creative process, especially when such gifted narrators as Mary Robinette Kowal are on board to work with us!
While the upfront costs of hiring talented human beings are more than we the authors and our small independent press can bear alone, with crowdfunding support, we can make this audiobook a reality! And it is SOOOO worth it.
