THE RANGER (4.5) by Rhonda Nelson: Soldier turned security expert Will Forrester is assigned to find a missing senior citizen, Theo Watson, who’s looking for a long-lost family treasure. Theo’s friend and protégée, guidance counselor Rhiannon Palmer, wants to assist Will, but he doesn’t want her help. She sticks with him until he gives in — and not just on the subject of Theo. Neither one wants a relationship, but it’s clear that there’s more to what’s happening between them than sex. Well plotted and wickedly sexy, this one’s got it all — including a completely scrumptious hero. A keeper.
