From School Library Journal PreS-Gr 1—The winning picture book team that created Extra Yarn (HarperCollins, 2012) is back together in this understated, humorous, and charmingly perplexing tale. Sam and Dave, who are either identical twin boys or friends who look astonishingly alike and share a sartorial sensibility, set out to dig a hole in the hopes of finding 'something spectacular.' With shovels in hand, the boys (with an eager terrier looking on) begin to tunnel into the soil, but they just can"t seem to find anything of interest. What works spectacularly is the clever play between words and pictures. As in Klassen"s This Is Not My Hat (Candlewick, 2012), readers are in on a joke to which the characters are oblivious. Namely, that each time the boys change direction, they narrowly miss discovering increasingly enormous jewels hidden in the earth. The book progresses with each verso showing the boys" progress, while the recto features simple text, mostly dialogue between the practical but unlucky explorers. About halfway through, a spread reveals a diamond so large it can barely be contained on the page it dwarfs the two boys and their trusty canine companion—but all for naught, since they decide to dig in a different direction. Exhausted and covered from head to toe in dirt, Sam and Dave decide to take a rest. Klassen"s use of muted earth tones and uncomplicated compositions is paired well with Barnett"s deadpan humor. As they nap in their hole, the dog continues to dig…until suddenly the trio is falling they soon land in a place that looks an awful lot like home. Small details reveal that this house and its inhabitants are ever so slightly changed. Are they dreaming? On the other side of the world? In a different dimension? Readers will have to puzzle that one out for themselves.—Kiera Parrott, School Library Journal
