Alternate Title: Oakleaf Bearers
This review contains spoilers for the first three books of the Ranger's Apprentice series.
Will and Evanlyn, with some help from Erak, have escaped slavery and drug addiction and are making plans to return to Araluen. That is, until Evanlyn gets herself kidnapped (again), and Will discovers an enemy of the Skandians, who is eventually interested in invading Araluen. This means he'll have to combine his powers with the Skandians so he can save Araluen and Evanlyn.
Everything from the first three books comes together in this book (Book five skips ahead in time). This means that, as there is a lot left to be tied up, it's simply action packed. Some great battles and fighting are in there. The story is very fast here and it was hard to put the book down. Luckily these books don't have too many pages, so I didn't suffer any sleep deprivation =)
Note: I read a Dutch translation of this book
