New York Times bestselling author Andy Griffiths invites readers to come hang out with him and his friend Terry in their 13-Story Treehouse - the first in a new illustrated middle-grade series filled with Andy and Terry's signature slapstick humor! Overtly, this is a funny story. Covertly, this is a book about how to tell (and maybe even write) a story. Andy and Terry live in a treehouse. But not just any old treehouse - a thirteen story treehouse, with a bowling alley, see-through swimming pool, secret underground laboratory, and marshmallow machine that automatically shoots marshmallows into your mouth. Life is pretty good for Andy and Terry, except... If they don't finish their next book by the end of the day, they will be kicked out of their beloved treehouse forever! But it's okay! They'll get right on it... if only the flying cats, big bananas, mermaids, sea-monsters pretending to be mermaids, and dangerous burp-gas bubblegum bubbles would stop wasting their time! New York Times bestselling author Andy Griffiths is at his storytelling best in this wild adventure, perfect for reluctant readers.
