FEARLESS (4) by HelenKay Dimon: A secret two decades old could cost Lara Bart her life. After stumbling across a murder and evading the killer who also wants her dead, Lara heads straight into the arms of the one man she swore never to speak to again: her ex-fiancé, Davis Weeks. The undercover operative is used to risking his life to keep people safe, but none have ever been as important as Lara. When the real killer sets Lara up to take the fall, then tries again and again to kill them both, Davis realizes they’re involved in something big. Dimon just keeps ratcheting up readers’ pulse rates with a tightly wound plot, punctuated with explosions, gunfire and passion.
