Looking for the name of a book similar to this, but don't think it is YA

Hi-yesterday while looking at reccomondations I came across one, but forgot to mark it as a to be read.

The storyline was about a man who had been in the games for about four hundred years, and he challenged a twenty five year old woman to a series of challenges. I thought that it had either Sin or Game in the title, but have checked everything. If you know this book can you please let me know! I have searched all day for it and cannot find it, in any list or under any tag.

It wasn't part of the Ghostwalker series, Feehan's series with "game" in the title. They are all human, well started out human, then genetically altered.

Michielle is right. Shadow Game is book one of the GhostWalker Series, but there is a different plot. Good books though. Are you sure you got the details right on the book you are looking for? I don't remember any book with that storyline.
