Ten-year-old Arden thinks the world has ended when she has to leave the house where she grew up to move to a tiny backyard guesthouse, built like a wooden boat. But things get worse when her best friend moves away and a pandemic causes school to be cancelled, leaving Arden's family quarantined and isolated in very little space. Her mother and brother are always trying to start businesses, her father is always trying to get her to do brave things, and Arden wishes people would just leave her alone so her world could go back to normal. As their neighbors leave town, shut down, and get sick, leaving their pets to care for, Arden becomes the safe-keeper of all the abandoned animals. As the pandemic wears on and touches home, Arden begins to see that saving animals is one thing--but does she have the skills and courage to try to save her family? A fiction in verse that reflects true stories of living big in small spaces during times of crisis, Ark is a modern retelling of the ancient story about a family and its animals striving to keep themselves and their world safe.
