Her father missing, fourteen-year-old Claudia Kobb is sent to be raised by a reclusive wizard and notorious outlaw, her grandfather, who has lived well beyond his mortal lifespan by way of a magical serum that bestows longevity. But the magic is fading, her grandfather is dying, and together they embark on a quest to find Claudia's father while avoiding the powerful warders of Subterranea, a vast underground city where those in power will stop at nothing to destroy those who oppose them.
The book really sets up for the future. You learn so much at the beginning that later become clear, important, and leaves you wanting to see what happens. There are many parts in the book that are a complete surprise and immediately leave you stunned and thrilled. It gives a lot of time to develop the characters in a way that you can easily visualize and in an entertaining way. The audiobook is incredible and the narrator did an amazing job. This book was much better than I first expected. Overall, one of the best books I've listened to in a while.
