Don't Let Go    by Harlan Coben Order:  USA  Can Dutton, 2017 (2017) Hardcover, CD, e-Book      Reviewed by Hilary Williamson I'm a long-time fan of Harlan Coben's for his gripping thrillers with unusual premises, ever twisting plots, and a steady stream of surprises. That all works for him again in Don't Let Go. Life has never been the same for New Jersey Detective Napoleon 'Nap' Dumas since the day fifteen years before that his twin brother Leo and the latter's girlfriend Diana were found dead on the railroad tracks. It made no sense to him, though others assumed they were high and fooling around on the tracks - just a tragic accident. At the same time, Maura Wells, the love of Nap's life, disappeared from it. Helped by his mentor Augie (Diana's grieving dad and captain of police), Nap has become a police officer, though one who often breaks the rules, as when he attacks a wife beater with a baseball bat. But he is obsessed by past events. Then another officer (a schoolmate of Nap's) is murdered and Maura's fingerprints are found in the car believed to have been rented by his killer - was she involved and where has she been all this time? Of course, Nap starts digging, and uncovers all kinds of secrets that have been kept from him - even by those closest to him - for all these years. Leo and his friends formed a geek squad, a Conspiracy Club of teens fascinated by a nearby Nike missile base (which when closed became a Department of Agriculture facility). One night, they saw something they shouldn't have, and Maura has been on the run ever since. Other geek squad members die - why? And will the truth set the survivors free? Read this engrossing thriller to find out. Note: Opinions expressed in reviews and articles on this site are those of the author(s) and not necessarily those of BookLoons.
