The 2nd book, "Kill The Dead" introduces an interesting new character: a Czech female porn star zombie hunter -- nice!. The 3rd book "Aloha From Hell" takes place mostly in Hell, as does the 1st half of the 4th book, "Devil Said Bang". The pacing of these books is of course whiz-bang, and each one does come to enough of a conclusion that you are not left resenting being hung over a cliff too much.
So there will clearly be more of these, I guess I'll keep reading them. I have concluded tho that I did like the Harry Connolly Twenty Palaces series better -- too bad it's been discontinued.
Meanwhile, I have three more novels by new authors, most suggested by tweets or retweets of people I follow on twitter. So, should I read some economics or politics, or am I still on vacation? We'll see, I guess.
