book 14 in the Time Warp Trio
Sam has come up with an idea that because everything in The Book has to do with inventions that perhaps an inventor created The Book. Many of the inventions in The Book are from the famous artist and inventor, Leonardo da Vinci. The boys go on an adventure, this time on purpose, to find Leonardo da Vinci and ask him questions about how The Book works exactly. But after they find him they have to deal with the army soldiers and generals for whom Leonardo is working for creating military inventions. Is da Vinci the inventor of the book and if so can he help them learn how to use it? To find out, read DaWild, DaCrazy, DaVinci by Jon Scieszka.
