★ Starred review in The Canadian Children's Book Centre's Best Books For Kids and Teens 2023 Fall edition!

In the second book of Caroline Fernandez’s Asha and Baz series, readers once more dive into the past—this time to learn about famous actor and inventor Hedy Lamarr! Computer class is off to a rocky start for Asha and Baz! They’ve been given a Coding Challenge and must correctly code instructions to send a digital frog across a computer screen. But they can’t seem to figure it out. With their reputation as the smartest kids in their class at stake, the pair turn to their magic stick for answers. They use it to draw their coding problem in the sand and are transported back in time to 1941 Hollywood to meet Hedy Lamarr, leaving them even more confused: How can an actor help them solve the Coding Challenge? But when they learn there’s a war happening and that Hedy Lamar has been hard at work inventing a device to help with war efforts, the kids realize her problem-solving skills may be just what they need. Coding, frequency hopping, and more await in Asha and Baz Meet Hedy Lamarr!
