The Isles of Elysium: Purge of Babylon, Book 6

Every journey has an ending. He's survived the Purge and battled overwhelming odds, but now Keo is back on the road and more determined than ever to fulfill a promise made nearly half a year ago. What he didn't expect - or want - was to end up in another bloody conflict. With the help of some old friends and some dangerous new ones, Keo must figure out a way to keep everyone he cares for alive. In a world where creatures maintain unquestioned dominion over the night and opportunists lord over the day, that's easier said than done. Keo is not the devil-may-care mercenary he once was, but he's never backed down from a fight before, and he's not going to start now. A year after the Purge, mankind is still an endangered species, but the Isles may finally offer the path to victory.
