curently rereading The catechist trilogy by alan dean foster.
read it some years back, long nough to forget the fine details.
Recommended.
One of my all time favourite books is his: Sentenced to prism.
Technically it's set in the humanx universe, but totally stand alone novel.
Sticking with mr dean-foster: The icerigger trilogy is just superb !
I need to track down the 2nd and third as I've currently only got the first of the books on my nook.
Like terry pratchett, many of alan dean fosters books are better the second third or even fourth time round.
I have no clue how many times I've read 'guards guards !'
I figure I'm into double figures by now.
Sometimes if you've read a 'heavy' book or something truly awful - like novelisation of a video game (avoid the assasin novelisations) you just want something guarenteed to be good.
Something you've read before is often the best way to go
