One-year-old Storm and his best friends, Jimi and Juul, form the Blockbusters: a secret society of curious explorers. Storm's mother is a painting restorer. In her home studio, she examines world-famous masterpieces. Children learn about art through reading, but the books are especially fun and exciting. Monet's Secret is the second book in the series. The Blockbusters are allowed to accompany Storm's mother to an art auction. There, they discover that a cartel is targeting the Monet painting that Storm's mother has just restored. During a new mission to stop the cartel, the Blockbusters discover that Monet had a secret and learn the connection between Impressionism and love.
