"Ever since Callie Marshall's husband died in the line of duty, leaving her and their sons behind, the boys have become her absolute priority. She's doing her best to minimize any risk to their carefully ordered world-- Ex-soldier Matt Bowden's middle name is "risk." Struggling to cope with his return to civilian life, he channels his energies into his adventure company. Callie has always been able to knock the air from his lungs, but she was his friend's wife and he's used to burying his feelings"--Cover verso.
