Bookroo's summary

Max seeks a fresh start away from his father's shadow in a quiet Texas town. When he discovers an injured octopus, Ursula, washed ashore, he vows to help her return to the sea. As Max forms unexpected friendships and uncovers surprising truths, his bond with Ursula challenges him to find his true strength. Can Max keep his promise and redefine himself, or will the summer's revelations change everything? Dive into a tale of friendship, discovery, and the courage to be oneself.

From the publisher

NATIONAL BESTSELLER - From the bestselling author of Song for a Whale comes a deeply moving story about a boy, an octopus, and the extraordinary bond that changes their lives forever. Max can’t seem to escape the big, looming shadow of his politician dad. But for the next few months, Max and his mom are going away to a quiet Texas beach town where Max can be someone else. Someone who doesn’t make dumb mistakes that embarrass his father–someone who knows how to be strong. He stumbles on his fresh start right away, when he finds an injured octopus washed up onshore after a storm. With the help of a local wildlife center and a couple of new friends, Max rescues the octopus–who they name Ursula–and vows to take care of her until she’s ready to return to the sea. But as their bond deepens and Max makes unexpected discoveries that turn his summer upside down, Max’s true strength will be put to the test. Can he keep his promise after all?
