FLINT - Ellie Masters

She designed the bomb. Now she's the only one who can diffuse it.

Former Army EOD instructor Carolina Sutton has been haunted by the training accident that killed one of her students. But when that student's bitter squadmate weaponizes her bomb design for a terrorist attack, the FBI needs her expertise-and they send Guardian HRS operative Flint Morrison to bring her in.

Flint has his own ghosts and a mission he can't afford to fail. Track Carolina through the California backcountry, convince her to face her worst nightmare, and keep her alive long enough to disarm the devices only she can stop. He doesn't expect to find a woman whose strength matches his own-or to feel a connection that threatens his legendary control.

As bombs tick down across California, Carolina must overcome her guilt and trust the Guardian who's sworn to protect her. But with assassins closing in and each device more deadly than the last, the only thing more dangerous than the explosives might be falling for the man willing to die to keep her safe.

He'll take any bullet to protect her. She'll face any bomb to save lives. Together, they're explosive.

A high-stakes romantic suspense featuring forced proximity, protective hero, competent heroine, and enough heat to detonate your kindle.
