This sweet book, about two mice who reside in a human home until they are trapped live and released in the wild, can be looked at as a metaphor for growing up, venturing out into the world on your own, making friends, growing old and saying goodbyes. Though it’s geared for young readers, its story packs a powerful message. Author/illustrator Lynne Rae Perkins turns the readers expectations upside down and provides a bittersweet surprise ending that left me completely unprepared for how choked up I got reading the last couple of chapters. Highly recommended for young and old alike.
