Ranger's Apprentice: The Battle for Skandia (Ranger's Apprentice, Book 4)

Still far from their homeland after escaping slavery in the icebound land of Skandia, Will and Evanlyn's plans to return to Araluen are spoiled when Evanlyn is taken captive by a Temujai warrior. Though still weakened by the warmweed's toxic effects, Will employs his Ranger training to locate his friend, but an enemy scouting party has him fatally outnumbered. Will is certain death is close at hand, until Halt and Horace make a daring, last-minute rescue. The reunion is cut short, however, when Halt makes a horrifying discovery: Skandia's borders have been breached by the entire Temujai army. And Araluen is next in their sights. If two kingdoms are to be saved, an unlikely union must be made. Will it hold long enough to vanquish a ruthless new enemy? Or will past tensions spell doom for all?

The battles and drama are nonstop in Book Four of this hugely popular epic.  more
