The illustrations are really cute.  The story is okay.  Edgar is a mouse who loves to build things from the food scraps he finds, but his best friend Toby keeps eating his creations, so he heads off to go where he will be appreciated, only to find mice everywhere keep eating his creations.  He heads home dejected, but finds a gift from Toby — his own set of inedible building blocks.  It’s fine, but I’m thinking the solution to the problem seemed a bit obvious.
