EngiNerds Strike Back

Ken and his inventive crew are back for a sequel to Revenge of the EngiNerds, and this time the comedy is loud and the stakes are planetary. The previous book ended with an extraterrestrial showing up, and he turns out to be exactly what he appears to be.

He has come to Earth as an envoy, sent to survey the area for a colossal futuristic billboard. Building it would mean destroying the planet, and the first place to be affected is the kids' own town. The EngiNerds refuse to let that happen, so they set out to protect their world from the alien's plan.
