Thirteen year-old Walter and his friend Chris are computer geniuses. Walter's younger brother, Tommy, is not; he prefers pizza and Super Mario to hard drives and gigabytes. That has never stopped the three from being close, until recently. Since the start of the school year Walter has been distant, locked in his room working on some top secret project with Chris.

One Friday night, the week before Halloween, a loud crash in the middle of the night draws Tommy to Walter's room where he discovers his brother missing, the room trashed and Walter's prized computer smashed.

Now it's up to Tommy to find his brother and delve into a world of technology, coding, and computers which he tried to avoid his whole life. With the help of Chris and Walter's mysterious online acquaintance NightHawk99, Tommy sets out on an adventure to find his brother. The journey to rescue Walter quickly escalates into a race to save humanity from a technological force dead set on world domination. Carousel Kids is a 78,000 word science-fiction adventure story with enough heart and excitement for middle-graders, all the way up to the adults who never grew up.
