I LOVE the illustrations!  They are rich and detailed and evoke a certain fairy-tale element to the setting.  Cleonardo is a young inventory is a family line of inventors, daughter of Geonardo and granddaughter of Leonardo.  With the town’s Grand Festival of Inventions approaching, Cleo is determined to help her father, but though indulgent, he’s a bit dismissive, sending her off out of his way.  With her grandfather’s help, Cleo sets up hr own workshop in the woods to design her own project.  On the day of the great festival, when her dad’s project runs into trouble, it’s Cleo’s inventions that help to save the day, and “From then on father and daughter always worked…side by side.”
