Time Castaways: The Mona Lisa Key by Shurtliff
From Liesl Shurtliff, the New York Times bestselling author of Rump: The (Fairly) True Tale of Rumpelstiltskin, comes a new middle grade trilogy about three city kids who get on the wrong subway train and wind up on a wild, magical family adventure throughout time. Now in paperback.
Mateo, Ruby, and Corey Hudson’s parents don’t have too many rules. It’s the usual stuff: Be good. Do your homework. And never ride the subway without an adult, EVER. The siblings have always thought that rule was a little silly, but they follow it.
Or at least they did until they wake up late on a school day and their parents are out taking care of an emergency at the museum where they work. With no other way to get to school, the Hudson siblings board the 6 train in Manhattan . . . and end up on a frigate ship in Paris—in the year 1911.
As time does tell, the Hudson family has a lot of secrets. The past, present, and future are intertwined—and a time-traveling ship called the Vermillion is at the center. Racing to untangle the truth, the kids find themselves in the middle of one of the greatest art heists of all time.
The adventure is just getting started.
