THE BABY MISSION 

An illegal adoption ring--using kidnapped babies--has to be stopped. To gather the necessary evidence, U.S. marshal Serena Summers goes undercover--as a married woman desperate for a baby. Her "husband" is her own partner, U.S. marshal Josh McCall, whom Serena blames for her brother's death. How can she act like a loving wife when she has to constantly fight her feelings for a man she isn't sure she can trust? The closer they get to unraveling the dark web of deceit, though, the more being Josh's undercover wife means putting her life--and future--in his hands.
