Luce and Alpha are identical twins. But on the inside, they couldn't be more different. When Luce and Alpha's parents split up, they go to live with mum and their Gra in his home in the forest. Mum has accepted a job heading up a rewilding centre that reintroduces wolves to the wild. This suits Luce just fine she can't go back to school and face everyone. Not after What Happened. And she loves the peace of the forest where she can watch the constellations through her telescope. But Alpha hates the forest and hates dad for breaking up the family. All she wants is to return to the city and follow her dream of becoming a basketball star. She doesn't want to hide away from the world, like her sister; she is like the Alpha Centauri, one of the brightest stars in the night sky. Things between Luce and Alpha have never felt worse. How can they be so alike and yet so far apart? When a new wolf cub is brought to the centre, Luce feels an instant connection. She names him Claw and they form a special bond. But Alpha thinks he should roam free, and together with her friends, they plot to release him. When news of Claw's disappearance hits, the future of the rewilding centre is at risk and Alpha's relationship with her family and her twin sister is shaken like never before.
