Andy Griffiths and the Treehouse series:

"Anarchic absurdity at its best. . . . Denton's manic cartooning captures every twist and turn in hilarious detail." --Publishers Weekly, starred review, on The 13-Story Treehouse

"Will appeal to fans of Jeff Kinney and Dav Pilkey. . . . The wonderfully random slapstick humor is tailor-made for reluctant readers. . . . A treat for all." --Booklist on The 13-Story Treehouse

"Twice the treehouse, twice the fun? You bet. . . . Denton's furiously scrawled line drawings milk the silly, gross-out gags for everything they're worth. Kids should be flipping pages faster than a pair of inflatable underpants can skyrocket the young heroes to safety." --Publishers Weekly, starred review, on The 26-Story Treehouse

"This zany sequel, as much cartoon illustration as text, is an almost nonstop adventure." --Booklist on The 26-Story Treehouse
