You Are Not Alone by Greer Hendricks, Sarah Pekkanen

Shay Miller wants to find love, but it eludes her. She wants to be fulfilled, but her job is a dead end. She wants to belong, but her life is increasingly lonely.

Until Shay meets the Moore sisters. Cassandra and Jane live a life of glamorous perfection, and always get what they desire. When they invite Shay into their circle, everything seems to get better.

Shay would die for them to like her.
She may have to.
