Leonora Bolt lives alone on remote Crabby Island, spending her days tinkering in a TOP SECRET laboratory under the watchful eye of her terrifying Uncle Luther. In Secret Inventor, everything changes when a mysterious boy named Jack washes up on the beach and reveals that Luther has been stealing Leonora's inventions and selling them on the mainland - kicking off a hilarious quest for justice involving an inflatable lobster, a furry otter and a very secret society.. In Deep Sea Calamity, Leonora isn't supposed to be building a submarine in a tree or turning local wildlife luminous - but when danger looms beneath the waves, her inventive genius is exactly what's needed. Eco Engineer sees Leonora crafting gadgets from old junk to take down Uncle Luther's latest scheme: Brightworld, a harmful amusement park hidden under a giant snow globe, in an eco-conscious adventure about engineering and environmental responsibility. Finally, The Great Gadget Games brings Leonora her first Christmas away from the island, invited to a prestigious inventors' competition run by Uncle Luther, who is secretly plotting to steal every contestant's best ideas.. Across all four books, Lucy Brandt combines laugh-out-loud humour with genuine STEM concepts, encouraging young readers to think like engineers while following a charming, resourceful heroine..
