Ally desperately wants "normal" for her half-sister Kayly, something she never had herself thanks to her videographer single mom. First on her list of to-dos is locating and contacting Kayly's dad, who promised her liberated mom he'd stay out of Kayly's life just as Ally's own dad once did. When Kat leaves the country on assignment, Ally takes matters into her own hands and drops in on the guy to introduce him to his baby daughter. But Kayly's dad doesn't live there anymore—Kayly's grown half-brother Zach does. And his shocking offer to help Ally find "normal" is nothing compared to what happens when revelation after revelation unfolds and no one is exactly what they seem.
