Fan favorite Ivypool takes center stage in Ivypool's Heart—a thrilling, super-long standalone adventure in Erin Hunter's #1 nationally bestselling Warriors series! It's been many moons since Ivypool lost her daughter, Bristlefrost, to the Dark Forest, yet Ivypool can't bear to move on. Even being named Deputy of ThunderClan feels meaningless in her grief. When Whistlepaw has a disturbing vision—one that could spell disaster for all the Clans—a group of cats is selected to go on a quest to investigate. Ivypool is happy to join their mission. Perhaps being away from her daily responsibilities will help her escape the painful memory of Bristlefrost's death. The cats set out on an arduous journey, facing everything from painful hunger to bloodthirsty dogs. But nothing can prepare them for what they find: a disgusting twoleg den that's caging a series of strange animals, including two who may have surprising ties to the Clans. In order to complete their quest and right a terrible wrong that goes back generations, the five Clan cats must help these creatures find their true home. But first, Ivypool must let go of the past, and her grief, if she is to have any hope of ensuring a future for the Clans—and for herself.
