The Harp and the Ravenvine (The Keepers#2)
Far away, drawn by an irresistible summons, a mysterious girl is making her way to the Warren, the Keeper stronghold. She wears the Ravenvine and is learning to wield its fascinating power; but this Tan'ji is damaged. There's no telling what will happen to the instrument or its Keeper if it cannot be made whole again. April's journey is long and dangerous, with strange new companions at her side and a pack of sinister hunters tracking her. Will she reach the Warren in time, and is it a safe haven, or will it offer only more danger?
While we learn a little more about the Riven and why they are trying to get the Tanu back, the new characters of April and Isabel are added in a very interesting way, and I enjoyed the fact that we aren't entirely sure if Isabel is good or evil. I'm not sure she knows herself! I'd be very interested in learning more about the Mazzoleni Academy and seeing what the Keepers can do to keep the Mothergates from running out of power. Certainly Mr. Meister will be very helpful at finally putting the threat of the Riven to rest!
If you get these books for your favorite readers, make sure that they are accompanied by a small harp, some yarn, and several fun objects that can be made into Tanu!
