Dex Putnam has been in love with her best friend Grace Standish since the fifth grade. Grace is smart, beautiful, and most unfortunately, straight. Life would've been perfect if Grace had only loved her back, but when Grace gets married, Dex knows it's time to move on. Then Dex meets Emma Lawson, and her life takes a whole new direction. Only trouble is, she never expected to have to choose between her best friend and her new love.

Emma Lawson is successful and happy except when it comes to love. She's been alone for a year and has no intention of giving love another chance, until falling for Dex changes everything. When Grace comes between them, Emma refuses to be second best. Can Emma show Dex what true love really looks like?
