Blood Debt - Project Prometheus, #4

Some secrets can kill. For Doctor Michael Banks, the price for his secrets could be his soul. As bio-terror ravages the Amazon, Michael's request for assistance from Project Prometheus brings him the unlikeliest of saviors -- a woman born of the desert, who might just hold the key to his redemption. Their partnership opens the path to stopping a chemical nightmare in its tracks, and a mysterious saboteur's mischief making turns deadly.
As the danger mounts, Michael will have to decide if his absolution is worth risking everything he holds dear, and a future he can't live without.
