Destroyer by Noah Mann

Two friends. One enemy. The battle to come may claim them all.
Eric 'Fletch' Fletcher faces the impossibility of his friend, Neil Moore, sitting ten feet from him in a dank cell. Very much alive years after he'd watched him die. The explanation, validated by Neil's CIA past, is convincing enough for Fletch, but the man who has taken them prisoner wants more.
Earl Perkins has dreams of power and has set his sights on the one place where resistance still flourishes. To conquer those who would stand in his way, he needs something he is certain either Fletch or Neil can provide. The secret location of a virus to be unleashed upon his adversaries.
Before that information can be extracted from the captive friends, a violent, daring escape sets them free. But free is only a word, as their pursuers will stop at nothing to bring Fletch and Neil back-dead or alive.
