Three words

After years of being a widow, Kaylee's mom has finally found love again. When Kaylee's new stepfather joins the family, he brings with him not only respite from the tiny one bedroom apartment Kaylee and her mother called home, he also brings his handsome teenage son Aiden. Aiden quickly charms Kaylee with his humor and friendly demeanor, and his best friend Damien is just as delightful. Before long, Kaylee realizes she has feelings for not only one but both of the new boys in her life. But the two boys have a more complicated relationship than Kaylee initially expects, and she quickly realizes she might have signed herself on for far more drama than she bargained for.
