"While spending the summer with their quirky inventor uncle, twin brother and sister Nick and Tesla are caught up in a bizarre mystery surrounding a spooky, rottweiler-guarded mansion. To get inside the mansion and uncover the truth, the siblings create lots of clever gadgets (like an alarm made from Christmas lights and a "robocat" fuelled by mints and soda) - and each awesome invention is accompanied by illustrated instructions so that you can build them yourself!"
