Marcellus, a giant Pacific octopus, has lived most of his life in the Sowell Bay Aquarium but yearns for the ocean's currents while he watches the humans who pass his tank with disdain. That is, until Tova, the night janitor saves him from dying on one of his nighttime expeditions. They form a sort of friendship that will change their lives and the lives of those around them, including Ethan the small town's grocer and Cameron an aimless newcomer. This warm and generous novel by Shelby Van Pelt is a celebration of the power of connection and of second chances.
