“A glittering tale of academic jealousy and ancient artifacts, *The Book of Gems* is a pulse-pounding adventure.” —Katherine Addison, author of *The Goblin Emperor* **** ** Some truths are shatterproof… It’s been centuries since the Jeweled Valley and its magical gems were destroyed. In the republics that rose from its ashes, scientists craft synthetic jewels to heat homes, power gadgetry, and wage war. Dr. Devina Brunai is one of these scientists. She also is the only person who believes true gems still exist. The recent unearthing of the Palace of Gems gives her the perfect opportunity to find them and prove her naysayers wrong. Her chance is snatched away at the last moment when her mentor steals her research and wins the trip for himself. Soon, his messages from the field transform into bizarre ramblings about a book, a Prince, and an enemy borne of the dark. Now Dev must enter the Valley, find her mentor, and save her research before they, like gems, become relics of a time long forgotten.
