Sir Gawain has a date with Death, but the Grim Reaper is about to get lucky in this steamy, magical modern-day adventure of knights, demons, and destiny. Dark Knight is the fourth book in a series of modern-day retellings of the myths and lore of Camelot. If you like fierce knights who would lay down their lives for their brothers and lose their hearts for their women, then you’ll love the Knights of Caerleon.
