According to nightlifer Roy Winklesteen, daylifers have no idea what they're missing. So, when a 2 a.m. glance out his bedroom window reveals a neighbor is hiding a secret of mythic proportions, Roy's summer break looks a lot more exciting. Seeking a cure for being the most ignored kid in all of fifth grade, Roy knows an awesome adventure will surely get him noticed in middle school. He watches and waits for the perfect time to move in for a closer look at the mysterious man who lives one street over. Roy's spy mission doesn't go as planned. Still, he manages to gain access into his neighbor's world--where mind-blowing inventions are more common than furniture and fighting crime involves transforming criminals into bumbling fools smothered in questionable goo. Every night with the neighbor brings Roy one step closer to the most daring adventure of his life. But even if he survives, he can never tell anyone about it.
