“What could be more treacherous than the realm of Briandalor, with its barbarians, wizards, warriors, assassins, and thieves? How about a modern middle school? You can’t help falling in love with this hilarious upside-down take on Dungeons and Dragons. I read; I cheered; I laughed out loud.” — Gordon Korman
“Played out with impeccable, hilarious logic, the plot leads up an adventuresome learning curve to a brisk battle in a local mall with animated mannequins, a really high-stakes duel involving the evocatively named phone game Oink Pop, and a final realization that Bríandalör’s dangers, lore, glittering treasures, and opportunities for daring exploits seem a bit pale next to those of . . . exotic suburbia.” — Booklist (starred review)

Praise for Hamstersaurux Rex vs. Squirrel Kong: “O’Donnell writes joyful silliness for readers with a budding adolescent sense of humor, and Squirrel Kong’s absurdism may resonate even with grumpy, neurotic adults. A pure blast of fun for readers who want something amusing and fast-paced.” — School Library Journal
