Harlan Coben’s plot-driven novels are some of the few that you can always feel safe spending your money on, even preordering, because you know they’ll be unputdownable. DON’T LET GO is another safe bet.

Nap, a policeman, lost his girlfriend, Maura, and twin brother, Leo, at pretty much the same time when they were all seniors in high school; Leo and his girlfriend, Diana, died, Maura disappeared. That was 15 years ago. Now Maura has resurfaced, and the circumstances of Leo’s and Diana’s deaths have come into doubt. Nap, still single, girlfriendless, and living alone, thinks the disappearance and deaths were related and strives to get to the bottom of them.

During his investigation, Nap discovers more and more about an old military installation in the neighborhood where they grew up. The deaths and, Nap believes, Maura’s disappearance seem to have something to do with what was going on there, some other government work. He learns more and more that Leo and Maura had not been telling him everything as he assumed.

Coben’s books are never a waste of time or money. So I’m happy to recommend that you do yourself a favor and pick up DON’T LET GO.
