Never Far Away by Michael Koryta

The New York Times bestselling "master" (Stephen King) of American thriller writing returns with an electrifying new novel about a mother seeking to reconnect with her children after a terrible trial tears their family apart.
Nina Morgan's bloodstained car was found a decade ago on a lonely Florida road. Forensic evidence suggested she'd been murdered, although her body was never found. Her disappearance left her infant children to the care of their father.

Once a pilot, mother, wife, and witness to a gruesome crime, Nina had to flee her old life to save her family. She reinvented herself as Leah Trenton, a guide in the Allagash Wilderness in northern Maine. She never expected to see her children again, but now tragedy has returned them to her-only they have no idea that she's their mother-and delivered all of them back into danger. "Aunt Leah" will need some help, and an old ally has a suggestion: an enigmatic young hitman named Dax Blackwell.

Never Far Away is a thrilling collision between old sins and new dreams, where the wills and ingenuity of a broken family will be tested against all odds.
