It is early spring, a turbulent, perilous time of sudden storms, frozen river fractures and drifting ice. Fleeing from a demon intent on devouring his souls, Wolf is swept out to Sea far from the Forest and his pack. The ocean too teems with danger: sea wolves, sharks and hunters of the deep, and the demon is gaining ground. Torak and Renn must race to save their pack-brother, battling the harsh, icy waves and merciless torrents. If they can't find Wolf in time, the bond between them will be severed for ever...

Run wild with Wolf Brother for the last time in a Stone Age world we all want to be part of, with three-million-copy-selling author Michelle Paver, Creator of Legends.
