My cousin is a time traveller (Nosy Crow Ltd)

The fifth and final book in the bestselling series sees Luke face his greatest fear yet, one that's surprisingly close to home... Luke's dad has bought a lot of gadgets recently and not one of them works as it's supposed to. Maybe it's because a machine-from-the-future is stalking Bromley, playing havoc with all the tech and trying to stop Star Lad going on a date. Could this be the Rise of the Machines? Luke knows what he must do - he just needs his fellow SCARF members to help or it will be the end of everything...
