Pre-Owned Scent of Magic, Healer Ser, by Maria V. Snyder. Paperback, Literature & Fiction, English

As the last Healer in the Fifteen Realms, Avry of Kazan finds herself in a unique position, no longer existing in the minds of friends and foes alike. Despite her need to prevent the megalomaniacal King Tohon from gaining control of the Realms, Avry is determined to find her sister and repair their estrangement. She must do this alone, as Kerrick, her partner and sole confidant, returns to Alga to summon his country into battle. Avry will do whatever she can to support Tohon's opponents, including infiltrating a holy army, evading magic sniffers, and teaching forest skills to soldiers. She must also figure out how to stop Tohon's most horrible creations yet: an army of the walking dead, human and animal alike, nearly impossible to defeat. War is coming, and Avry is alone, unless she figures out how to do the impossible once again.
