The only want home is to survive.

Caleb and Ronan are best friends. It doesn't matter that Ronan is a dog and Caleb is a middle-schooler. They've been together their entire lives and traveled the world together with Caleb's family.

But now, with Ronan too old for such adventures, Caleb has chosen to stay in Seattle, settling down with his grandfather in a quirky retirement community. Things should be calm here, maybe even boring. But then tragedy strikes, and Poppy is rushed to the hospital. Suddenly, Caleb's world erupts in chaos and he and Ronan are separated.

Desperate to find each other, the two friends set out on an impossible journey. But a deadly storm is brewing and predators lurk, and they have no idea where the other is. Can they find their way back together--and to Poppy--before it's too late?

Critically acclaimed and beloved author Martha Brockenbrough weaves a heart-pounding adventure that is equal parts survival story and finding your place in the world.
