Washington's Dirigible (1997) 325 pages by John Barnes
This is the second novel in the timeline wars series. Mark is hired as a CruxOp by ATN and is sent to training where a couple of new characters are introduced. After a short adventure in training he is sent on his first assignment. This is an alternate history where there is no American Revolution and George III is King that has been tutored by Ben Franklin.
The closers have been in this timeline as well. Mark lands in Boston, but learns that George has changed drastically, and that somehow people know him already.
A few battle scenes, lots of historical characters, some weird inventions all folded into a fast paced story. This book can stand on its own without having read the first one. I enjoyed it.
