Imminent Danger by Jannine Gallant

Can they rekindle their love before a killer strikes?

Brody Grant had it all—wealth, the woman of his dreams, and a young son he loved more than life. But his world came crashing down the day River was kidnapped and murdered. Torn apart by grief, he creates Counterstrike, a covert team of highly trained operatives whose sole mission is to rescue kidnap victims.
After losing her only child, Arden Grant tried to pick up the pieces and go on. But her husband is distant, immersed in his perilous quest to save others. Leaving Brody to live in the backwoods of Vermont, she searches for solace in simplicity.
Brody finds fulfillment in his work, even if he can’t forget the only woman he ever loved. Until he crosses paths with a vicious psychopath with a very personal connection. On a single-minded crusade to track down his adversary, Brody unwittingly puts Arden squarely in the crosshairs of a ruthless murderer.
Arden wants no part of the danger her ex-husband brings into her safe but lonely world. Except neither of them can find peace until they stop a madman and put the past to rest. And maybe discover a future together they both believed was lost forever.
