There's a lot twelve-year-old B doesn't know--like what their new name should be after coming out as nonbinary. Or what it would feel like to finally feel at home after moving around to different foster families for years. But there's one thing B does know: they want to be a dog trainer when they grow up. And when they meet Gooseberry--a feisty stray dog who seems as wary of strangers as B does--B feels an instant connection. With Gooseberry, B could have everything they want: a family of their own, and a dog to train. And B's newest foster parents agree to let B adopt him.

But training a dog isn't as easy as B expected. Gooseberry is anxious and barely lets B pet him, let alone train him. Will Gooseberry ever feel at ease with B? And how can B teach Gooseberry to trust, when they know so little about trust themself?
