Gumbrella loves cute little animals, and she's the "take-charge" type. So when her brother, Trumbull, comes home with a hurt mouse, naturally she starts an animal hospital. Soon the house is filled with sick animals, and Gumbrella couldn't be happier. There's only one problem. Months later when they are all feeling fine, Gumbrella can't bear to let them go home. In the first book that Barry Root has both written and illustrated, his wry humor captures all the vulnerability behind even the bossiest of big sisters.
