Pendragon Cycle

The “Pendragon Cycle” series by Stephen R. Lawhead is a retelling of the Arthur and Merlin legend and reimagines things so that Merlin’s mother comes from Atlantis. The novels take place in both the fifth and sixth centuries, and bases these stories on different historical texts and mythological ones. (like History of the Kings of Britain, Mabinogion, and some works by Geoffrey of Monmouth, plus some other ones too) The series has gotten acclaim for how creative it was in telling the Arthur legend and being historically credible.
