The Horn Book Guide (2008) gave
There’s No Such Thing As Ghosts
a starred review!
"Equipped with his trusty butterfly net, a boy goes ghost-hunting at the haunted house in his new neighborhood. Though he doesn't see a single ghost, young viewers will spot a whole bevy of them--short and squat, with big smiles and rosy cheeks--blithely going about their business. Yellow highlights keep the black-and-white illustrations, often in black silhouettes, warm and sunny."
(And they continue to recommend it every October!)
And School Library Journal pointed out how this fun and friendly ghost story "will find a welcome place in collections, not only for Halloween, but also year-round."
