I'm a big fan of Greek mythology, so was really excited to read this book. I enjoyed the world-building and story, although some of the twists and reveals where a little obvious to me to have the intended effect. I still very much enjoyed the journey of these character through the underworld, the tasks they face along the way and seeing their relationships with one another grow and develop. 

The first half is a little slow in places; the second half is more gripping. Overall, I thoroughly enjoyed this book, and would recommend to any Greek mythology fans. I'll definitely read book 2!

Thank you to the publisher and NetGalley for the ARC of this book, in exchange for an honest review.
