In this humorous manga novel, a high school sophomore starts a secret social club to help teen girls figure out which boys to date and which to avoid.

Everyone knows that—with rare exception—girls are fatally drawn to jerks! Upon discovering the sobering truth, Penny takes it upon herself to form her own underground club to identify these boneheads and cure her girlfriends of their addiction to them! But starting a school-wide revolution may be more complicated than she thought! Designing clothes is one thing, but designing a new standard for the battle of the sexes may be beyond even Penny.
