The Deepest Poison

Octavia Leander, a young healer with incredible powers, has found her place among Miss Percival's medicians-in-training. Called to the frontlines of a never-ending war between Caskentia and the immoral Wasters, the two women must uncover the source of a devastating illness that is killing thousands of soldiers. But when Octavia's natural talents far outshine her teacher's, jealousy threatens to destroy their relationship-as time runs out to save the encampment. Fans of Beth Cato's debut, The Clockwork Dagger, will love this journey into Octavia's past-as well as an exclusive excerpt from the sequel, The Clockwork Crown!
