The Eugenics Wars, Vol. 1 by Greg Cox.
Everything is true. That is, all those details of history that Star Trek revealed about the late twentieth and early twenty first are TRUE. You don't remember them? Well, this book will jog your memory.
This is a real treat, where Cox takes a tapestry of details from EVERY Trek series (except Enterprise) and makes a seamless whole of them. The Eugenics Wars and the rise of Khan Noonien Singh are the focus of this series. Volume one really doesn't get to the wars, but it tells us of the life of Khan, and we get to see Roberta Lincoln and Gary Seven trekking about the globe helping humanity avoid extinction. Lots of fun! I'm torn now because I read this in paperback, and I'll have to wait till vol 2. comes out in paperback to buy it... hopefully the library will get the hardback so I can read it soon.
