I don't have one favourite author but I find myself following several different series and then hoarding books on my TBR list (yes, I know there is a separate thread for this but I am still in denial). I know when I have read them I just want more NOW! I think the worst wait was for the latest Thraxas book - For a couple of years it didn't look like it was going to be published. I have 2 Kevin Hearne books to read but I am waiting for the one published at the end of the Month before I start to read them.
But for the moment I am currently re-reading my Thraxas books (Martin Scott aka Martin Millar) before I read the latest one.
