The Child of the Wolf (Time's Children Saga: Book One)

With no memories of her past, Belle Willow Smith wakes up in Camp Half Blood, hiding from something she can't remember. The only thing linking her to her past is a key and visions of events from a man called the Doctor. Oh, and her new friend who no one can see but Bella. Yep, just a normal day at camp. Bella doesn't know she's the strongest weapon in the universe. She doesn't know that her family is the most dangerous one in all of time and space. She doesn't know what she is, or what she's capable of. She doesn't know that not knowing her past is the way it needs to be for her-and the universe- to be safe. But she can't control that. Someone else holds the cards. That someone- the one who has the item everything in the universe wants, the one who has the weight of two universes on his shoulders, the one that the one with Bella' s memories(in a fob watch)- is a curious, very ADHD child of Hephestus. And when some of the most powerful demigods are kidnapped, only a small group of kids can save the day. But what if it's more than they expected? What if they realized they're part of something much greater? ((DISCLAIMER: All demigods belong to Rick Riordan. Everything related to Doctor Who belongs to BBC. I just own Belle, Brooke, Erza, and Dylan))
