Dangerously Entwined - Aegis Group Lepta Team, #5

The mission: Don't die:Retired Marine Grant Anderson is used to tough situations. He's never shied away from putting in hard work. Perhaps he should have known a secret romance with his fellow team leader, Melody Nguyen, would be his toughest job of all. Melody has had it with alpha men and secrets. After a year-long romance that went nowhere, she ended it and is determined to make the most of her career.
When an old enemy attacks, Melody and Grant will have to put aside their differences to save the team. But that's easier said than done when their lives and their hearts are on the line.
