Missing.

Storm warning: FBI Agent Lucy Kincaid and her colleague Nate are racing a severe storm, but the weather is the least of their worries when two prisoners escape and take a child hostage along the way. Lucy and Nate must try to rescue the boy and survive the storm, without letting these violent criminals get away.

No way out: Lucy's husband, Sean Rogan, and his brother, Kane, go missing on the eve of a family wedding, and she's forced to put aside her fear and work the case. Someone is looking for a missing girl - they think Lucy's future sister-in-law knows where she is - and will do anything or kill anyone to learn the truth.

A deeper fear: Lucy and Sean head to Sacramento for a conference. But the upcoming drom demonstration - and the fact that Sean didn't come home last night - is the least of the couple's worries when the drone's operator is found, barely clinging to life.
