Surprisingly believable (once you realize the transistor was invented in 1925) alternate history novel of how the UK could have used what sounds like early micro-computers during World War II. Recommended.
Second written, and second chronologically of the Mrddlers In Time series. Like the first, stays on the boundary between homage and fan fic, this time echoing the Weber/Ringo and Niven/Pournelle Empire of Man series. The author has improved his craft from the first book, without losing his eye for good plot.
Time travel/alternate history somewhat in the 'Connecticut Yankee In King Arthur's Court' (or' Crosstime Engineer') vein. Reads like the Mission Diary it's framed as - the writing is promising journeyman work - but for a REALLY interesting mission. The main characters are pretty bloody minded - nukeing a medieval city to get rid of maybe 5% of the population would take a thicker skin than mine, for example. Heinlein's 'Time Enough For Love' is referenced, staying just this side of the homage/fanfic line. Was surprised to find this one offered for free - it's worth paying for. There is certainly worse out there from major publishers. The author might - if he hasn't already - consider submitting to Baen Books, which has published a deal of similarly themed work.
