A favourite of mine, an an alternative historical fantasy about four damaged people, a one eyed Welsh wizard, an exiled heir to the Byzantine throne, a female physician to Lorenzo de Medici and a German vampire engineer, working against the Byzantine Empire. The struggle takes them to England after the War Of The Roses, where deadly dynastic squabbles threaten to turn the kingdom on its head. Clever, elliptical, occasionally horrific, full of magic and intrigue and mystery and betrayal. I wish I could write more about it but I'm still tired and my eye still hurts.
