Fallen From the Sky — Susan Hart

Airline incidents have skyrocketed in North America, and FBI agent Cathy McPherson races to uncover the cause. As the public grows fearful, McPherson and her team sift through a maze of possibilities. They suspect a rival manufacturer might be sabotaging equipment to gain market advantage, but evidence remains elusive. McPherson's instincts lead her to consider terrorism or a vengeful customer targeting the industry after losing a loved one in a crash. The pressure builds as another plane goes down, and McPherson faces intense scrutiny from her superiors. She presses forward with an unyielding determination, aware that each hour wasted could mean more lives lost.
