The Immortal Pool

Calista Orchard, a 14-year-old orphan, with no recollection of parents, runs away from her foster home. Again. When running, she is mugged by two people- but they turn out not being people at all! They're The Fallen, and they want to suck her blood. But before they succeed, she is saved by a winged boy, and taken to a place where magic isn't unheard of. The Haven is a safe house for people with unusual abilities, and it's the eighth in the world. There, Calista meets the mysterious Edge, who she knows nothing about, the good-natured Marlowe, unless you're Damien Parker, a young werewolf boy, and Simon, who can read minds. She is taught how to use her newfound powers by The B, a woman with nearly no emotions, and is happy, for once. But, there is a threat attacking The Haven, and soon the world, and Calista is in the middle of it.
