In this entry in the classic hit series, Stacey worries her best friend is growing up too fast and they’re drifting apart. Stacey can’t wait! Her best friend from New York, Laine Cummings, is coming to Stoneybrook for a whole week. She can spend a day at SMS, attend club meetings, and maybe go to the Valentine Dance. But from the minute Laine arrives, nothing goes as planned. She thinks Stacey’s sleepover with her friends is childish, and can’t believe Stacey’s still into baby-sitting. Laine’s more used to hanging out at high school parties with her fifteen-year-old boyfriend. Stacey doesn’t want to lose her childhood friend, but Laine’s growing up way too fast for Stacey. Is this the end of their friendship? The best friends you’ll ever have—with classic BSC covers and a letter from Ann M. Martin!
