Dealing with her father's murder would've been easier if Cassie were the Chosen One. But there are no prophecies, no grand design of fate, no world to save, only a line of succession from her father to her. Cassie inherits her father's role as the Keeper of the Haldori, a gem that is the source of the extraordinary abilities that the diovar use to manipulate the world around them-and no one's happy about it. Not the man who killed Cassie's father hoping to claim the Haldori for himself. Not Cassie's aunt, who still believes the Haldori should've gone to her instead of her younger brother. Especially not Cassie, who just wants her father back. With her power-hungry family pressuring her to abdicate and a murderer stalking her, Cassie must learn to use the enormous power in the Haldori. But the gem has its own sentience, and if she fails to control it, she will lose more than the last, true connection she has left to her father-she just might lose herself.
