Review Quotes:
Andy Griffiths and the Treehouse series:
"The Treehouse books are a perfect balance of minimal text, maximum black-and-white drawings packed with jokes, and unbelievable amounts of nonstop action, gags and exuberant, anarchic storytelling. These books seem ideally designed to make a new reader feel--and be--successful." --The New York Times "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 "Look, if you haven't heard of the Treehouse series by now, you probably don't know many kids. ... Chock-full of mischief, wonder and imagination." --The Sydney Morning Herald, on The 156-Story Treehouse
