THREE STARRED REVIEWS! • From two of the most acclaimed and beloved picture book makers today, Mac Barnett and X. Fang, comes a hilarious trickster tale like no other. A sneaky sheep has a proposal for an innocent boy that will change both of their lives forever: a brain swap!

Farmer's son Felix knows that Tom Nancy is a clever little sheep. Still, Felix is surprised to learn that not only can this sheep talk, he also has a marvelous machine stowed away in the barn that will allow them to switch brains for the day. Felix agrees to Tom Nancy’s idea of a swap, and it works! Felix finds that life in the pasture as a sheep is interesting. But Tom Nancy discovers that being a boy who wrestles and eats sandwiches is simply stupendous! So when Felix tells him he’s ready to switch back, Tom Nancy has another idea . . . 

A deliciously subversive story that delivers some just deserts, Tom Nancy will have readers of all ages laughing out loud and on the edge of their seats.
