Leo never imagined that time travel might really be possible, or that the objects in H. G. Wells’ novels might actually exist. And when a miniature time machine appears in Leo’s bedroom, he has no idea who the tiny, beautiful girl is riding it. But in the few moments before it vanishes, he recognizes the other tiny rider: himself! His search for the time machine leads him to the New York Circulating Material Repository, a magical library that lends out objects instead of books. Hidden away in the Repository basement is the Wells Bequest, a collection of powerful objects straight out of science fiction novels. And when Leo’s adventure of a lifetime suddenly turns deadly, he must journey to 1895 to warn scientist Nikola Tesla about a dangerous invention.
