Ranking good in the UK

Wolves of Rome seems to be doing pretty good so far on Amazon - the highest rating I've managed to get so far for any book I've released in the past. Right now it is doing best in the UK where it is ranked #18 in Historical Fiction. I'm still looking for reviews - I know it takes time but just a friendly reminder.
