Leonardo da Vinci gets a do-over

the long version

"The passing of great Renaissance master Leonardo da Vinci- artist, anatomist, engineer, inventor- marked the end of an era. The world hasn't seen a visionary like him since ... until now. On a school trip to Florence, three American middle school students think they're in for a treat when a man who claims to be Leonardo da Vinci, brought back to life with a mission to better humankind, crashes their tour. Too bad he isn't really the celebrated Master of the Renaissance ... or is he? Will the students be able to help Leonardo evade the mayor of Florence's selfish grasp so he can complete his quest before his time runs out? Tag along with Tad, Max, and Gina as they assist Leonardo on his quest, discover the secrets of his life, and teach the Maestro about science, math, history, art, and more!"--
