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!
