Hey Kid, Want to Buy a Bridge?

"Joe, Sam, and Fred are really good at meeting people, making friends-and enemies-in all different places and times. But this time everything is completely different! It's Brooklyn, it's the 1880s, and some crazy guy's trying to build a bridge all the way across to Manhattan. Meanwhile, their great-granddaughters, who have inherited <i>The Book</i> are doing a little time-traveling of their own, and they need some help. The guys just want to get back to their simple, ordinary twenty-first century lives. But will they find a way out before things get too far out of hand?<br> <br> ""You say there's nothing in your library for boys to read? Never fear, the Time Warp Trio is here."" (<i>Booklist</i>)"
