Special Agent Zeke Cabot and Anne Reynolds are both excited and a little wary as they take steps to commit to their budding relationship. But like the unpredictable weather in the mountains of New Mexico, their path to happiness is anything but smooth. Zeke continues to struggle against debilitating bouts of PTSD and flashbacks.

Anne still copes with the lingering pain from her divorce and wonders if she's ready to take another chance on love, especially with a woman.

A danger from a past case Zeke thought was closed threatens both their safety and the strength of their trust. But Zeke and Anne are determined to overcome their personal obstacles and learn to defy gravity enough to keep them grounded in love.
