Mo and Jo Don't Stink!

Mo and Jo, aka the Boulder Brothers, join JUMP-INTO-CHAPTERS with a series of pre-hysterical escapades. In the first chapter, Me Stink?, something’s smelly! Is it Jo? Is it Mo? Is it both? Though kids will know who’s the real odor-offender, they’ll have fun watching the caveboys try to figure out the source of the stench.

Hide and Peek, Chapter 2, has Jo teaching Mo how to play his favorite game. But does Mo really not understand the rules? Or is he a peek-and-cheater? And who will have the best ideas for warming up in Me Cold!? Will a prehistoric beastie mind when they try to borrow some fur?

Though Mo and Jo both speak caveman-ese, educators can be assured that the accompanying narration will offer kids a correct rendition of grammar and sentence structure.

But don’t be surprised to hear Boulder Brothers’ fans declare, “Me want more MO AND JO!”

Pierre Collet-Derby: Pierre Collet-Derby is a Montreal-based animation artist and children's book illustrator.

"Collet-Derby’s illustrations feature a palette of bold earth tones, with touches of contrasting color... A limited vocabulary, oversized font, and lots of word repetition will quickly build reader’s confidence, and the goofy mini-plots and earthy humor will have them looking for the sequel." “The Bulletin of the Center for Children's Books

"The word count is only a step above Mo Willems’s 'Elephant and Piggie' titles (Hyperion). In fact, these caveboys’ antics are sure to attract Willems’s readers who are ready to move on to other titles. VERDICT Funny and adventurous, Mo and Jo will appeal to new readers." “School Library Journal

"The bold orange-and-brown illustrations are loosely in the style of cave drawings, though the two brothers are thoroughly modern in their mischievous attitudes and escapades. Lynn’s dialogue, consisting of basic vocabulary words; chuckleworthy narration; and large-format, easy-to-read layout are endearingly entertaining and create fun and accessible experiences for a new reader. Sure to leave young fans demanding more! More Mo! More Jo!" “Booklist
