The winged knights—magically altered humans—are the only ones defending the portal from Av’lor to Earth. With defeat imminent, they find an unlikely source of hope in software engineer, Kathryn.
Kathryn doubts her life could get any worse after the death of her mother and daughter. She realizes her mistake after she arrives on Av’lor with only part of her house and hungry creatures looking for their next meal. Once the knights bring her under their protection, she discovers their angry commander is far from welcoming.
Sir Lanclor, Commander of the Knighthood, lives with the curse of betrayal. While the treachery occurred lifetimes before, few see past his guarded shell to the grim man beneath. Barely holding the Knighthood together, his grip tightens when Kathryn joins their ranks. Her stubbornness and surprising strength not only energizes the knights, but also makes Sir Lanclor question his self-imposed isolation.
With the approach of an invading army, Kathryn and Sir Lanclor must find a way to end centuries of war and save two worlds.
