When Brutalia's ever suspicious Queen is forewarned of a new enemy - from a nearby island called Bonrock - Mort is worried. As a pacifist, he's a firm believer that strangers are just friends they haven't met yet. Then he and his best friend and fellow pacifist Weed are sent to the island to investigate.

But Bonrock is a warm and welcoming place, with luscious landscapes and tropical waters. Mort's relieved - there's no need to fight! Until they stumble upon something terrifying ... Perhaps there really is trouble in paradise?
