Two Girls One Boy — Janet Quin-Harkin

City Girl, Country Girl...
Caroline's thrilled to find out she's got a long-lost cousin exactly her age. But she's horrified when Chrissy comes to spend a year with her family. Caroline's a reserved and polite only child -- now she has to share her life with a loud, unsophisticated, embarrassing farm girl. But when she complains, her parents tell her Chrissy just isn't used to city ways.

Then Chrissy begins spending lots of time with Caroline's boyfriend, Alex. Now Caroline's really had it. She can't be expected to share everything! But can she win Alex back, or has she waited too long to put her foot down?
