Time Castaways: The Mona Lisa KeyHardcover, 18 September 2018

From Liesl Shurtliff, the New York Times bestselling author of Rump: The True Story of Rumpelstiltskin, comes a thrilling new middle grade trilogy about three city kids who get on the wrong subway train and wind up on a wild, magical mystery-adventure throughout time.

Imaginative, daring, and packed with fun, Time Castaways is perfect for fans of Escape from Mr. Lemoncello's Library and Percy Jackson.**

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. But when the siblings wake up late for school, they have no choice but to break a rule. The Hudson siblings board the subway 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.

And the adventure is just getting started.
