Six years after her brother's death in an F-18 fighter jet crash, Lieutenant Ambrosia ("Sia") Soto must investigate another pilot fatality aboard the U.S.S. James McCloud. A routine training mission claimed the life of a senator's son, and Sia must shelve her family demons to find answers. There's just one hitch. Leading her on the investigation is NCIS agent Chris Vargas: her former lover and the man she blames for her brother's death. Can Sia bury old feelings for Vargas and overcome the past? And is there someone aboard the McCloud who knows more about these pilot "accidents" than they're letting on? Sia has more questions than answers, and what she uncovers will rewrite history as she once knew it.
