The Warden and the Wolf King

Janner Wingfeather's one job is protecting his brother and sister, which gets nearly impossible when the Fangs of Dang attack Ban Rona and the three of them are split apart — Janner lost in the hills, Leeli fighting from the rooftops, and Kalmar headed for the Deeps of Throg with a secret he hasn't told anyone. This is the last book about Gnag the Nameless, and everything the Hollowsfolk spent the whole winter getting ready for finally happens.
