Wolf pack
(Book)

Most of the time, Noble, Argus, Harlan and Tora are like any other teenagers. Prowling the halls of their high school in search of new crushes and true friendships, all while trying to keep up their grades. Except these teens are anything but ordinary. Discovered as wolf cubs in the wilderness of Redstone Forest, the pack knows their adoptive parents are the only humans they can trust with their shape-shifting secret. So whenever the siblings want to wolf around, they race to the forest to run and relish their special bond. Until the terrible day a TV crew films their shocking transformation and Tora is captured by a scientist determined to reveal her supernatural abilities to the world. Now the brothers will do anything to get their sister back. Even if it means taking their powers to a whole new level by becoming werewolves for the very first time--something their parents warned them never to attempt. But once the teens go to the dark side, will they ever make it back to the only life they've ever known?
