Mercy finds herself seconded to the ATF to infiltrate an anti-government militia. Intelligence suggests they have illegal firearms and explosives and plan on acting against the government.
Meanwhile her fiancé, Truman, is investigating a series of execution style murders in his town.
The Mercy Kilpatrick books are a rare pleasure for me. These are the books I wait for and when I finally get them I just want them to go on forever. A Merciful Promise is another seat of your pants adventure in a series that is yet to disappoint me.
Many thanks to Montlake Romance for providing me with this review copy.
