Black Harvest (Noah Wolf Book 13)
Noah and the team go after the most despicable organization they've ever encountered: human traffickers that deal not only in slaves, but also in harvested organs. Using organ donor recruitment groups on college campuses, they choose their victims carefully and keep them prisoner until their organs have been sold on the black market.

Because the organization is so widespread, the team goes in three separate directions to take them out. Unfortunately, that leads to Jenny, Renée and Sarah all being captured while Noah is all the way across the country from them. While Noah uses Wally's latest tricks and breaks every rule to get to them, the three girls are faced with a terrible choice. The only possible hope is for one of them to sacrifice herself, but which one will it be?
