Bask in the gleeful rebellion of three younger siblings as they seek bold adventures far away from their older siblings in this hilarious early graphic novel from a Pulitzer Prize-winning cartoonist.

The youngest of seven siblings, Lucy, Bruce, and Oliver are sick and tired of being told that they are too little to do the things their older siblings do. In a bout of bored frustration, they band together to form Sib Squad--a club of their own dedicated to having "amazing, mind-blowing adventures." And adventures they have! Award-winning cartoonist Steve Breen crafts a riotously fun look at sibling dynamics that will be beloved by downtrodden younger siblings everywhere.

In this first book in the series, the Sib Squad launches the club at their tree house headquarters, then find themselves drawn into multiple adventures that include wishes at a wishing well gone wrong and an unlikely encounter with a younger sibling from outer space. As young readers delve into the trio's hijinks, they will find themselves struck with uncontrollable giggles and an unquenchable desire to seek adventures of their own.
