Dave Spinner is a calm and rational teenager. So when he discovers a group of kids his age branding themselves the Council of Older Siblings and claiming that there existed a centuries old war between them and the League of Little Brothers, the first thing Dave does is laugh. But as clues start popping up around him, all pointing towards an evil scheme devised by the leader of the League of Little Brothers with the goal of bringing down Older Siblings, things are no laughing matter. Alongside the bossy leader of the Council of Older Siblings and his slightly incapable and very overweight best friend, Dave embarks on a race against time to stop the little siblings from unleashing an anti-aging chemical on the older siblings and turning them all into helpless babies. Join Dave on his journey as he discovers the lengths to which some little brothers and sisters will go to in order to get their way. In this heart-warming and humor-filled story in the fashion of many classics, themes such as loyalty, betrayal, the greater good, and blind-faith are explored at a level where readers of all ages can come to understand and appreciate the nature of siblinghood.
