Ranger's Apprentice 3, The Icebound Land

Will and Evanlyn are bound for Skandia as the captives of the fearsome Skandian wolfship captain, Erak. Halt has sworn to rescue Will, and he will do anything to keep his promise - even defy his King. Expelled from the Rangers, Halt is joined by Horace as he travels through Gallica towards Skandia. On their way, they are constantly challenged by freelance knights - otherwise known as thieving thugs. Horace knows a thing or two about combat, though, and he soon begins to attract the attention of knights and warlords for miles around with his uncanny skill. But will they be in time to rescue Will from a life of slavery?
