ALL'S FAIR IN SIBLING RIVALRY AND WAR.

After nearly losing her family and her life, Olivia Talbot is trying to leave the world of artifact hunting behind. But an adrenaline junkie unsuited for a 9 to 5 job can't hide herself forever, especially when deadly operative Dale West comes knocking with off-book work for his covert organization.

It'll be "easy", West says—just a trip to the museum. But a deranged former soldier is seeking to reunite the pieces of Gungnir—spear of the Norse god Odin—which is capable of starting war, and this job is much bigger than anyone has let on.

Followed by the dogged son of a tabloid mogul, competing with her archaeologist older brother, and still struggling to trust West against her better judgement, Livi will venture into an ancient underwater city in the Mediterranean to stop the dawn of a new war. But the spear of a god has plans for them all, and power not even she might be able to withstand.
