Durren Flintrand never expected to be paired with a party of misfits—a wizard afraid of her own magic, a rogue who can’t stand anyone, and a warrior who’s not the sharpest sword in the armory. To survive Black River Academy, they must outwit rat armies, dark sorcerers, and homicidal unicorns. Their only hope? Level up, work together, and face an ancient darkness that could end their journey before it begins.
