Servant of the Dragon, by David Drake
This is the third book in the Isles series, and Drake is still going
strong. Garric, Sharina, Cashel, and Ilna, and various friends, continue
trying to save civilization, while the threat this time is the
culmination of a plot a thousand years in the making. I won’t give away
any details, save to say that our heroes aren’t fighting by themselves;
the bad guys have been making free with the mummy of a long dead wizard,
and said long dead wizard isn’t happy about it. The only problem is that
he’s, well, long dead.
