Crackling with excitement and sexual tension, Shadow Hawk (4.5), by Jill Shalvis, is a book you won't be able to put down if you like adventure and hot romance. Conner Hawk and Abigail Wells, ATF agents in Wyoming, have communication problems. Hawk is attracted to her, but trauma at Abigail's last posting has her determined to stay away from men, and she appears to hate Hawk. Within the first few pages, the two are sent on a raid that goes terribly wrong: Hawk is shot and framed as the very terrorist mole he is looking for. He handcuffs Abigail to himself so that he can protect her, but she thinks he's taken her hostage. From there the tension and the sex escalate and never stop.
