A Fighting Chance by K. Alex Walker

The first time FBI Special Agent Joel Lattimore meets the group led by Gage Wolfe, he immediately realizes one thing: these guys aren’t the boardroom businessmen they claim to be. Their presence is too threatening. Plus, one of them walks around outfitted to the hilt with lethal weapons and looks like his middle name is “murder-for-hire.”
Joel gets his confirmation when he discovers they’re an elite, multinational paramilitary ghost unit.
And they want him on the team.
But joining the team exacts a heavy price.
After a life-changing mission in Angola, he returns to the U.S. to find that the woman his life has revolved around since he was only sixteen years old no longer wants to be part of it.
No matter what he’s had to sacrifice, her happiness has been his sole purpose for more than half of his life. So, even as their divorce leaves the one-year mark in its rearview mirror, even as she moves on, dating and thriving…he’s unable to shake the belief that there’s no one else for him.
That is, until he finds himself caught in a war between his mind and his heart.
His mind tells him that Ayesha Savea, the widow of the team’s only fallen member, is just a friend. For years, she’s been just a friend. However, as they grow closer, as he feels more like part of a family than someone on the outside looking in, his heart tells him he’s headed for a journey that will transform everything he’s ever believed about the right way to fall in love.
