A thwarted assassination attempt drags Caissa Ocren into a secret war between elemental spirits and dragon worshippers. More accustomed to solving puzzles than wielding swords, she undergoes a crash course in survival from a mercenary minstrel, a shape-shifting druid, and a legendary spirit warrior. An ancient book may hold the answers she seeks, but understanding requires the memories of a wizard. With time against her, Caissa faces the hardest lesson of all—how to serve when the cost is her life.
