Night angel nemesis

"After the war that cost him so much, Kylar Stern is broken and alone. Hes determined not to kill again, but an impending amnesty will pardon the one murderer he cant let walk free. He promises himself this is the last time. One last hit to tie up the loose ends of his old, lost life. But Kylars best, and maybe only, friend, the High King Logan Gyre, needs him. To protect a fragile peace, Logans new kingdom, and the kings twin sons, he needs Kylar to secure a powerful magical artifact that was unearthed during the war. With rumors that a kakari may be found, adversaries both old and new are on the hunt. And if Kylar has learned anything, it is that ancient magics are better left in the hands of those he can trust. If he does the job right, he wont need to kill at all. This isnt an assassination-its a heist. But some jobs are too hard for an easy conscience, and some enemies are so powerful the only answer lies in the shadows"--
