The Keepers: The Harp and the Ravenvine

Horace F. Andrews and his friend Chloe are Keepers of magical objects of extraordinary power.  But as the presence of a new Keeper is made known, they are drawn into a struggle to find out who she is and where her loyalties lie. A gripping sequel to The Box and the Dragonfly, the first book in Ted Sanders's Keepers series, hailed by the New York Times Book Review as a "satisfying and original quest tale." 
As Horace and 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. Accompanied by a mysterious woman with a power of her own and the young boy leading them in the right direction, April is being pursued by a pack of sinister hunters. Will she reach the Warren in time, and will it offer safety or only more danger?
Ted Sanders's series has the feel of classic fantasy with a science fiction twist, and this second book, The Harp and the Ravenvine, will thrill readers with adventure, intrigue, and the unexpected at every turn.
