My Cousin Is a Time Traveller

My Cousin is a Time Traveller by David Solomons  
Luke is stunned to discover that his cousin is a time traveller—and even more shocked when she warns him that intelligent machines are plotting to take over the world. To make matters worse, Zack has decided to ditch his superpowers and embrace life as a regular teenage nerd. That leaves Luke to save the day (again!), whether he likes it or not. Bursting with wit, twists, and wild adventure. This hilarious series is a perfect pick for fans of sci-fi comedy and reluctant heroes.
