At first I thought I would find this book boring...really fictional about mice and moles and other tunneling creatures. But the story developed my interest as much as many adult mysteries, better than some. If the reader can get over the distaste for the characters, the story is pretty exciting and poses some interesting thoughts about life, wanting to live forever, searching for eternal life and what it costs. I therefore recommend this book to young readers who may just be starting their adventure into the genre of detective novels.
