The Juliet Club by Suzanne Harper

Kate Sanderson has been burned by love. From now on, she thinks, I will control my own destiny, and I will be reasoned and rational. But life has other things in store for Kate. Namely, a summer abroad studying Shakespeare's Romeo and Juliet in the very town where the star-crossed lovers met, Verona, Italy. Kate is thrown together with two other American teens and three Italians for a special seminar—and for volunteer duty at the Juliet Club, where they answer letters from the lovelorn around the world. Can Kate's cool logic withstand the most romantic summer ever? Especially when faced with the ever-so-charming Giacomo and his entrancing eyes . . . ?
