Bloodline

Galilee, 1025. Infiltrating an ancient citadel, a Templar knight uncovers a holy treasure long hidden within the fortress's labyrinth: the Bachal Isu -- the staff of Jesus Christ -- a priceless icon that holds a mysterious and terrifying power that promises to change humankind forever.
A millennium later, Somali pirates hijack a yacht off the coast of the Horn of Africa, kidnapping a young pregnant American woman. Commander Gray Pierce is enlisted for a covert rescue mission into the African jungle. The woman is no rich tourist: she's Amanda Gant-Bennett, daughter of the U.S. president.
Suspicious that the kidnapping masks a far more nefarious plot, Gray must confront a shadowy cabal which has been manipulating events throughout history...and now challenges the current presidency.
For this unique mission, SIGMA is aided by a pair of special operatives with unique talents: former Army Ranger Captain Tucker Wayne and his military war dog, Kane. But what should be a straightforward rescue turns into a fiery ambush and a deadly act of betrayal, as Gray and his team discover that the hostage is a pawn in a shattering act of terrorism with dark repercussions. And the danger is only beginning...
