I like an obscure sci-fi writer named R.A. Lafferty. Arrive at Easterwine is one of my personal favorites, but his work of historical fiction about Native Americans in Oklahoma, Okla Hanali, is arguably his best book and very good.
Wolfram von Eschenbach's Parsifal is the greatest medieval epic, by turns humorous, amorous, and mystical. I recommend the Cyril Edwards translation.
Ted Hughes' selected translation of the Metamorphoses, Tales From Ovid, is well done if you are interested in mythology in late antiquity.
