New York Times best-selling authors Raina Telgemeier and Gale Galligan team up and return to The Baby-sitters Club in this super special graphic novel! Kristy, Claudia, Mary Anne, Stacey, Dawn, Mallory and Jessi are the luckiest baby-sitters in the world. This summer, they’re going on what is sure to be the best vacation ever: a plane ride to Florida, a cruise to the Bahamas on an extravagant ship, and then back to Florida for three days of fun at a huge amusement park! The BSC has a million adventures, of course. And they still have time for what they like best of all: baby-sitting!
