The battle between boys and bots is on in this funny, fast-paced novel. Ken is an EngiNerd: one of a super-smart group of friends--all nerds--who have been close since kindergarten. They may be brainiacs, but they´re just like everyone else: they fight with one another, watch too much TV, eat Chinese food, and hate walking their dogs. Well, maybe not just like everyone because Ken´s best friend Dan has been building robots. He then secretly sent one to each of the EngiNerds, never letting them know he´s the mastermind. At first Ken is awed and delighted: what kid hasn´t dreamed of having a robot all their own? Someone who can be their friend, clean their room, walk the dog, answer homework questions...how amazing is that? But be careful what you wish for: Dan´s robot, Greeeg, may look innocent, but his ravenous consumption of food--comestibles--turns him into a butt-blasting bot. And once the other robots ´come alive´ it´s up to the motley crew of EngiNerds to not only save the day, but save the planet!
