Burner (Gray Man #12) by Mark Greaney

With all the excitement that we’ve come to expect from a Court Gentry story, the Gray Man is back, and all hell is following right behind him. When a sensitive computer file is stolen from a Swiss Bank, it sets in motion a worldwide manhunt.

Court finds himself between both the CIA and the Russian mob and only someone with his skills has a hope of emerging alive. This series just gets better rather than stale. The odds are constantly higher with each installment, and this one is no different.
