Valentine's Day is approaching at Bailey Elementary, and the school cafeteria is suddenly serving up more than just regular lunch. When a cheerful new lunch monitor named Mrs. Rosenbloom arrives, things get incredibly weird. She starts handing out unusual heart-shaped hamburgers and baking cookies that seem to have a strange, magical effect on everyone who eats them. Before long, students and teachers alike are acting completely out of character, acting silly and swooning all over the school. Eddie, Howie, Liza, and Melody are not about to let this bizarre behavior slide. They quickly suspect that Mrs. Rosenbloom is not just a friendly cafeteria worker, but might actually be Cupid in disguise, shooting magical love spells through the lunch menu. Grab a tray and join the gang as they launch a funny, fast-paced investigation into their school's mysterious new lunch lady. You will have to read closely to help the kids figure out if love is simply in the air, or if an ancient mythical matchmaker has completely taken over the Bailey City cafeteria.
