Sebastian’s memories have been restored, and so has his sense of purpose. He intends to stop the Hunters, free the rest of the cryptomorphs in Pentepolis, destroy Hell’s army, and kill the Countess and Lord Ashmar. Meanwhile, he has two Mates to balance, more secrets to unravel, and new colleagues he may or may not be able to trust. He doesn’t know it, but he’s playing a dangerous game of chess with demons, and there’s more happening than anyone in his party realizes. With chess, there’s always an endgame. The only question is whether the dark queen’s gambit will be successful, and if the golden king will be left standing when the game is done. Endgame is a M/M dark science fiction fantasy romance intended for mature audiences.
