Cornwell's an excellent medieval fiction novelist; his Archer series (Holy Grail), Warlord Chronicles (Arthur) and Saxon Tales (Alfred the Great) are very well written. Its funny, I used to read Sharpe's Regiment books and only realized that it was the same author after reading the first of the HG series that my wife surprised me with. The HG series actually has a fourth book...even tho the HG by this point had been found, it uses Thomas as the main character, albeit about a decade after the events in HG series.
