Michael Z. Williamson’s latest, A Long Time Until Now is out in Baen’s eARC (electronic Advanced Reader Copy) edition. I read the twelve sample chapters Monday, bought the book yesterday and just now finished it.
The précis is that two MRAP vehicles containing a Lieutenant and nine troops in a convoy in Afghanistan vanish from the present and end up about 15 centuries millennia in the past in the same physical location. There are natives. And later, other groups displaced from other times and places.
That was a GREAT read, and this one’s not a trilogy you have to wait two years for the next serving of. Strongly recommended.
