The secret time machine and the Gherkin switcheroo

"Marcus is in trouble. He didn't think his friend Laurence would actually believe him when he said that his super brainy aunt built the very first time machine. He only made up the story in a spur-of-the-moment bid to win a silly argument! Now how on earth will he make the story come true? In a quirky new adventure starring the most unexpected of friends--a worm and a bird--Simone Lia pulls out all the theatrical stops to deliver a laugh-out-loud companion to They Didn't Teach This in Worm School!"--Provided by the publisher.
