Never read Stainless Steel Rat but I did read Stars and Stripes in Peril (also by Harry Harrison). I think there is another one Stars and Stripes Triumphant or something like that I need to read.
But usually for alternate history I read Harry Turtledove. A new book came out in the American Empire series. Read his Worldwar and Colonization series.
In the last two weeks I finished the 9 books of the Wheel of Time series and am disappointed it doesn't even seem close to ending even with book 10. I will probably wait till 10 comes out in paperback. I also finished Star by Star.. (I finally found it in a 2nd hand store).
Currently reading X-Wing: Book 2 about the NR conquest of Coruscant. I've never read the Xwing series.
I have one Tom Clancy book.. Executive Orders.. bought it for $5.00.. it was a slow read. I prefer just watching his movies and playing Ghost Recon... lol
