When Brooke's family moves to a weathered farmhouse miles away from the life she knew, she feels more lost than ever. Her old friends, her school, her familiar routines - all gone. What's left is a lonely stretch of farmland and the ache of starting over. But then, in the dim light of the barn, Brooke meets Artax - a black rescue horse with a storm in his eyes and a reputation for being untamable. He's restless, scarred by the past, and doesn't trust easily. Neither does Brooke. Drawn together by quiet understanding, girl and horse begin to bridge the distance between fear and trust. As Brooke struggles to find her place in a new town and her parents focus on fixing up the farm, she discovers that healing takes time - and sometimes, it comes in the form of an unexpected friendship. But Artax isn't hers to keep. And as the weeks pass, Brooke must decide if she's brave enough to fight for the bond they've built... or strong enough to let him go. A heartfelt story of resilience, belonging, and the powerful connection between a girl and a horse, Goodbye, Artax is perfect for fans of middle-grade and young adult.
