Every child needs a hero to be inspired by, whose hard work and talent led to success; someone just like them.

For Kojo, that's his grandpa Lenny. There is no one Kojo looks up to more, and one day, he hopes to be a SUPER INVENTOR, just like him. Turns out, he needs to learn a few things first.

Through the experiments, catastrophes, and successes of young inventors Kojo and Esi, kids will meet the brilliant Black heroes of STEM, and discover the lasting legacies that they've left behind. Time for Trouble is the first title in a trail-blazing series, and kids will be inspired by the real-life heroes they discover between the pages. The companion reference title, Super Inventors, which features in every chapter book, is the must-have read for any young inventors looking to kick-start their own career in STEM.
