Not the Bodyguard’s Widow by Lorin Grace

An expectant widow hiding from her husband’s killer. A bodyguard willing to save her at all costs.

A malfunctioning security alarm sends bodyguard Alex Hastings to Indiana to investigate on behalf of Hastings Security. Instead of an empty house, he finds a beautiful intruder bold enough to demand he leave.
Kimberly Thompson has one goal in mind, stay alive. When the local midwife proposes a marriage of convenience between Kimberly and Alex, Kimberly wants to refuse, but she’ll do anything to save her baby. After all, it will only be for a few months before they can get a quiet annulment.
As danger mounts and their feelings grow, Alex hopes to catch a killer and save the woman he now loves.
