Ryan Harper solves problems with a gun. Single mother Frankie Castor uses her positive attitude and cheery disposition. Can they work together when their lives depend on it?
For Frankie, life is good when everyone around her is happy. She thinks nothing of dropping her Boston career and returning to her small-town Montana home to help her aging mother. When Frankie meets a troubled stranger, she doesn't hesitate to help him, unaware she will soon face choosing between her daughter's life and matters of national security that could cost the lives of millions.
For Ryan Harper, keeping his country safe is his life--first as a Navy SEAL, then as an operative for Blackthorne, Inc., a private organization that goes where Uncle Sam can't. Banished from the field after two missions go south, Ryan can't believe anyone thinks he would leak vital information. Unable to use Blackthorne's resources, he returns home, taking with him a computer file he thinks might hold the key to the leaks. Before he can unlock its secrets, he's sidetracked by Frankie and her daughter, Molly, who open a place in his heart he didn't know existed. When terrorists descend into the Montana mountains, Ryan must decide between fighting for his country or fighting to rescue people he loves.
These are character portraits not a hook.
Start with how they meet. What puts them in jeopardy? Who are the terrorists and why are they in Montana? Vacation?
I like the first paragraph but after that you need to get to the action and be specific about who the bad guys are.
