Dreams of Significant Girls by Cristina Garcia (Used, Paperback)

Vivien, Shirin, and Ingrid have nothing in common and like each other even less. Thrown together as roommates at a prestigious Swiss summer program, the girls must contend with Vivien's earnestness, Shirin's prickliness, and Ingrid's rebelliousness. Over three tumultuous summers, they navigate the shoals of first loves and heartbreaks, nervous breakdowns and family disappointments to find that differences dont matter as long as you are there for the people who are there for you. 

National Book Award Finalist Cristina Garcia delivers a poignant tale of frienship in her first novel for young adults.
