The third instalment in a STEM-sational series which inspires a love of STEM learning in children aged 5+ through a unique blend of adventure stories and interactive play. Read the book, solve the quests using stickers and learn STEM skills in immersive ways never done before.

Meet Lilli and her best friends Leo and Bea - three endlessly curious kids with BIG imaginations. When they unite to solve a challenging science problem, they turn into SUPERHEROES Lillicorn, Leo Zoom and Bea Bumble and journey to a world full of magic, adventure and quests. And now they want YOU to join in the mission and the fun.

When Leo's mum challenges Leo, Lilli and Bea to figure out how to power a model airplane using a special biofuel that can be made from an ingredient in their very own garden, the friends start investigating and return to Questland in search of a solution. Upon arrival, they discover that the evil Lord Grumble is up to his dastardly tricks, stealing energy throughout Questland from the sun, wind, water, animals and crops, and sending it back to his secret hideout on Black Rock Island. Adventure and excitement await as the friends work together to crack this latest case. Can you help them defeat evil Lord Grumble and return the stolen energy to Questland?

This unique interactive story with hands-on activities is expertly designed in line with the Key Stage 1 and early Key Stage 2 Computing, Maths and Science National Curriculum to help children develop their STEM (Science, Technology, Engineering and Mathematics) skills in innovative new ways. Children develop over 12 STEM skills including problem solving, coding, sequencing and algorithms as they complete each interactive quest...and discover their inner superhero along the way.
