What is Found by Ilsa J. Bick

The worst was past.
John Worthy thought he had conquered his demons. Gotten over his guilt over Roni Keller’s death. Banished regrets about the boy he’d been: a kid forced to make an impossible choice. Yes, he was doing just fine until Hank Patterson showed up.

But now the worst is yet to come.
Sent on a covert mission to Afghanistan’s remote Wakhan Corridor, John and his Brotherhood Protectors partner, Taz Davila, are tasked with retrieving Roni Keller’s remains. Plagued by delays, rockslides, and the weather, there is also a clear and present danger which John, a man with more than his share of secrets, is determined to keep.

And the past is only prologue.
As they drive further into the mountains, John delves deeper into his own tortured past: from the trauma of 9/11 to the disastrous explosion at Abbey Gate—and the reasons behind the doomed, off-the-books rescue mission which cost Roni her life.

But when Taz is gravely wounded, John is left with yet another impossible choice: abandon his partner or lose his one shot at redemption.
