In this second book of the Mistmantle chronicles, led by an orphaned squirrel, the adventures of a group of animals continue as they form new alliances, and Urchin discovers a secret about his past.

King Crispin and Queen Cedar have just had a baby daughter--Princess Catkin--and everyone on Mistmantle Island gathers for the joyful celebration of the Naming Ceremony. But the day after, the princess suddenly disappears. Urchin and all the brave captains are dispatched to bring back the princess, but come back empty-handed. All clues point to Linty, an older squirrel who had gone mad with grief when two of her children had been culled during evil...

When evil interrupts the coronation of Crispin, the squirrel, on the isle of Mistmantle, Urchin, guided by the Heartstone, must embark on a perilous journey to a hostile island where he makes a startling discovery about his own past.
