When Cedar Branch, Idaho, is devastated by what is purported to be a nuclear transportation accident, Mia, the lone survivor, finds herself secured for mysterious reasons by the CIA. When Nicholas Price from Homeland Security is abruptly pulled off the case, he springs Mia, and they go off on an "unsupported" investigation of their own, which ultimately leads to the highest levels of government and a secret bioterror weapons-development facility. While Mia copes with her grief over the deaths of her friends, she learns of Nick's suffering over his sister, and the two fall hard for each other. With nonstop action interspersed with a slow unveiling of clues and great sex scenes, debut romance author Davis has created a wonderful genre-blend of thriller, suspense, and sexual tension.
