When Rhydian Morris joins Maddy Smith's school in Stoneybridge, the small rural town where she lives, they form a seemingly unbreakable bond, sharing a secret they try to keep, even from Maddy's best friends, Tom and Shannon. They are Wolfblood's, part human, part wolf, with extraordinary powers, speed and senses, along with the ability to transform at will. As the wild wolf side of their nature struggles for supremacy with the human side, they try to find their rightful place in the world. This brings them into conflict with Maddy's tame Wolfblood parents, werewolf hunters, their friends and others in school. When untamed, wild Wolfblood's dramatically enter their lives, claiming Rhydian as one of their own, it puts them both in jeopardy, testing their love and trust in each other and those closest to them. But each triumph over adversity brings unforeseen twists and turns, and the human world begins to home in on their secret with dramatic, heart-rending consequences for both of them.
