When Mona the Mouse stumbles across the wondrous world of the Heartwood Hotel in the middle of a storm, she desperately hopes they'll 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 the Heartwood Hotel is not all acorn soufflé and soft moss-lined beds. Danger lurks, and as it approaches, Mona finds that this hotel is more than a warm place to spend the night. It might also be a home.
