Firestorm by Jeanette Windle

Sara Connor, the reluctant heroine of CrossFire, barely escaped the ruins of the Cortez drug empire. All she wants now is to figure her life out and find sanctuary in Miami. But the enemy is back, bringing terrorism to the heart of her homeland. This time more is at stake . . . an entire nation is caught in the crossfire.

As the child of missionary parents, Jeanette Windle grew up in the rural towns of Colombia, which are now guerrilla hot zones. Her research and writing is so realistic that it has prompted government agencies to question her to determine if she has received classified information.
