The Trigger — Jacqueline Diamond

A serial bomber is on the loose. Bomb squad specialist Nora Keyes knows only one way to flush the killer out: set herself up as his next target...

Bomb squad specialist Nora Keyes teams up with arson investigator Sam Prophet to catch a serial bomber. Sam has never trusted Nora's Wild West style, and Nora considers Sam too by-the-book. Neither wants a working relationship...or a personal one. But that changes when Nora's undercover scheme goes terribly wrong and Sam must risk his life to save her. For the first time ever Nora knows real fear. Not for herself, but for Sam...the man she loves.
