A rip-roaring picture book adventure from superstar pairing Malorie Blackman and Dapo Adeola. Over the shimmering ocean, up the huge, high mountain, through the deep, dark forest . . .
 
Join two intrepid adventurers as their imaginations transform their house into a wild wonderland - and their big brother becomes a mighty monster. A joy to read-aloud with its cumulative refrain, and full of funny, relatable characters, this is a contemporary celebration of creativity, fantasy and family.
