Bloodline by James Rollins Book Trailer

Immortals walk among us, but immortality has a price,and someone is about to pay. Sigma Force will be sacrificed unless they find the key to who kidnapped the president’s pregnant daughter and why her unborn child is worth killing for. Horrors will be unleashed, all to preserve the Bloodline. http://www.jamesrollins.com or https://www.facebook.com/sigmaforce
