After five years, Alex Stern and Rafe Hazelton have what seems to be the perfect marriage. Alex is entering his last years of residency and Rafe’s veterinary business is busier than ever. For Rafe, all that is missing is a child, but Alex, afraid of ending up to be a man like his father, isn’t as sure. He doesn't want to make any mistakes. When a new patient enters the hospital, Alex is drawn to the young, desperately ill single mother, who shares her fears for the future of her young son. Rafe worries about the toll on Alex becoming emotionally invested in a patient, yet he too can’t walk away once he meets the little boy, and together they vow to help in any way possible. Families are not always born of blood— love is a gift no one can plan for. And sometimes from the darkest of tragedies, the brightest light will shine.
