America's favorite series returns with a new look and a Netflix TV show. Now that Dawn and Mary Anne are friends and sisters, Dawn wants them to do everything together ― share a room, talk all night long, wear each other's clothes. But living with Mary Anne isn't exactly what Dawn expected. Mary Anne brags about having a date to the school dance, her kitten throws up on the rug, and she hogs Dawn's baby-sitting jobs! Dawn's always wanted a sister. Instead, she got Mary Anne, the wicked stepsister of Stoneybrook! Ann M. Martin is the creator of The Baby-sitters Club, which has more than 190 million books in print, making it one of the most popular series in the history of publishing. Her novels include A Corner of the Universe (a Newbery Honor Book), Belle Teal , Here Today , A Dog's Life , On Christmas Eve , and the Main Street and Family Tree series, as well as the much-loved collaborations P.S. Longer Letter Later and Snail Mail No More with Paula Danziger. Ann lives in upstate New York.
