Plus with the family stress of his mother's surgery, he needed something to keep his mind occupied. But little sister Cherry had her own schemes in play, and events more serious than high school pranks or mother's cancer were about to focus the world's attention on this little northern town. One of the Small Towns, Big Ideas series of Young Adult science fiction adventures by Henry Melton.
