from the back of the book:
Everyone knew the legend of Christopher Sim. Fighter. Leader. An interstellar hero with a rare talent for war, Sim changed mankind's history forever when he forged a ragtag group of misfits into the weapon that broke the back of the alien Ashiyyur.
But now, Alex Benedict has found a startling bit of information, long buried in an ancient computer file. If it is true, then Christopher Sim was a fraud.
For his own sake, for the sake of history, Alex Benedict must follow the dark track of a legend, into the very heart of the alien galaxy -where he will confront a truth far stranger than any fiction imaginable...
I'm enjoying McDevitt's work and looking forward to more. He's my new favorite science fiction author.
