PART TWO It's December and festive cheer is in the air; Lizzy is preparing for the annual Harmon family get-together and is looking forward to celebrating her first Christmas with Aaron and Jack as part of the festivities. But the road to happiness is never a straight one and with the added pressures of new co-workers, conflicts within her family, finding time for her newfound love life and a potential group of killers roaming Quantico, will Lizzy get her perfect white Christmas? Will she be able to face a part of her past that she'd rather forget? And will they all manage to escape unscathed?

Dr. Lizanne Harmon looks to have a pretty charmed life - she has a secure job as a gynecologist, a home with two beautiful girls and has no immediate health concerns, because apparently having intense gardening competitions with the neighbors doesn't actually run in the family. But when a shocking discovery drags Lizzy into the world of the BAU and onto the trail of a serial killer, she is forced to hug her family a little tighter and re-evaluate her relationships with her friends and colleagues. And can love really bloom when you're looking over your shoulder for the eyes of a murderer - even if that love is in the form of Supervisory Special Agent Aaron Hotchner?
