PreS-Gr 1—A cute cover is the best part of this square, lift-the-flap paperback featuring the popular dog and his family. Marley has been chosen to play lead reindeer in the school Christmas play, but when it comes time to perform he disappears. By lifting the flaps, children will discover where he's gone, but the bigger mystery is how he got away in the first place since it's his leash that seems to have disappeared. Marley's fans probably won't mind the thin plot, but this pedestrian holiday offering is additional at best.—Teri Markson, Los Angeles Public Library
