"When last we met, the EngiNerds were battling a horde of ravenous robots, but in this latest caper, they're on the hunt for just one rogue robot. But who knows what kind of mayhem one mechanical creature can cause? And why is Ken the only EngiNerd who's worried about the runaway robot? The rest of the crew seems be missing in action and Ken fears it's because of Mikaela Harrington. She's the new girl in town who's UFO and alien-obsessed and wants to join the EngiNerds. But as far as Ken is concerned, the EngiNerds are Y-chromosome only, no X's allowed! Will Ken allow a rogue robot and a know-it-all, genius girl to wreak havoc on the entire universe? He just might not have a choice!"--Provided by publisher
