Lucy and Alpha used to be the Wonder Twins, two hearts beating as one. When Mum's new job rewilding wolves means they have to move to the forest, that changes.

Lucy loves being close to nature, but Alpha wants to follow her dream of basketball glory. They've become like distant universes, drifting further apart.

Then a new wolf cub arrives at the centre. Lucy names him Claw and they form a special bond. But Alpha thinks he should roam free, and she plots to release him. When news of Claw's disappearance breaks, the future of the rewilding centre is at stake.
