Ted Sanders's acclaimed Keepers series returns with The Harp and the Ravenvine, the eagerly awaited sequel to The Box and the Dragonfly, hailed as a "winding fantasy adventure" by the New York Times Book Review. This classic tween fantasy has a science fiction twist and will thrill readers with intrigue, magic, and the unexpected at every turn.

As Horace F. Andrews and his friend Chloe adjust to their newfound talents--Horace can see the future and Chloe can walk through walls--a girl called April is drawn toward the Keeper stronghold, the Warren. She comes with a Tan'ji of her own, though it is damaged and there is no telling what will happen if it cannot be made whole again. Will she reach the Warren in time, and will it offer safety or only more danger?
