When Mona the mouse stumbles across the wondrous world of the Heartwood Hotel in the middle of a storm, she desperately hopes the staff will let her stay. As it turns out, Mona is precisely the maid they need at the grandest hotel in Fernwood Forest, where animals come from far and wide for safety, luxury and comfort. But it's not all acorn soufflé and soft, moss-lined beds. Danger lurks nearby, and as it approaches, Mona has to use all her wits to protect the place she's come to love. Because this hotel is more than a warm shelter for the night. It might also be a home.
