Harry Turtledove

An excellent science fiction/fantasy writer who is know as "The Master of Alternate History". Has several full series based around the major wars of the century, including "The Great War" series, which starts with the novel How Few Remain, a story set just post a civil war in which the north lost. He is best known for the novel Guns of the South, another novel in which the south wins the civil war...thanks to the intervention of some time travelers.
Some other series he's done include "WorldWar", in which the Second World War is interrupted by the interference of alien invaders, and the "Videssos Cycle", a story centered around an alternate Byzantium. He's also done several novels like Guns of the South, which site outside any series. Most of these are novels filled with excellent short stories.

Harry Turtledove was born in Los Angeles, California in 1949. He is considered the premier Alternative History author of our times. Mr. Turtledove has taught ancient and medieval history at such varied institutes as UCLA, Cal State Fullerton and Cal State LA. Obviously he enjoys Los Angeles.

Other than his own books, Mr. Turtledove has been the principal editor of many many short story compilations, and it is considered a wise marketing ploy to tack his name on a book in a very large font if it contains a bastardized version of history. He has also published a translation of a ninth-century Byzantine chronicle, as well as some serious scholarly articles in some well known history journals.

He is married to Laura Frankos, a fellow novelist, and has three daughters, Alison, Rachel and Rebecca.

Harry is a prolific writer, but surprisingly, his books are very well written. They read as a series of narratives, with each of the characters lives giving the details of the events occuring around them. In his longer series, Harry takes well known historical figures and works them into his epic stories. The premise of most of his works is a simple change at one point in history, and how it affects all life afterwards. Described as What If? stories, they are a unique experience of any one who has a knowledge of the original historic event.
