Penny Wright has loved her brother's best friend Mason for years, but she's only been sleeping with him for one. Mason is in her bed one night and in the arms of someone else the next, but no matter how hard Penny tries to pretend it's all in fun, this secret, non-relationship is tearing her apart. She's trying her best to be flexible, but let's face it. A girl can only bend so far until she breaks. When it all comes to a head in a nothing-will-ever-be-the-same-again kind of moment, Penny is left with one breathtaking choice. Stay and face the music, or run away with Mason and try to find out, once and for all, if what they have together is real. This series is complete! Each book can stand alone, but the series is best enjoyed in order.
