A real bugbear of mine, in fantasy literature, is names that blatantly look like they were cobbled together at random off a Scrabble board. I don’t mind if all the names in a book are like this (at least it’s consistent) but when it’s a mixture of ‘decent sounding’ names and names that... well... aren’t then that bugs me even more. It’s like only doing half a job!
While ‘Katsa’ is a quite a cool name and ‘Randa’ (the King) just about passes muster I have real trouble getting into a book where I’m giggling at names like ‘Po’ and ‘Tealiff’. That’s just me though and it may be that any other reader wouldn’t have a problem with names like these (I doubt it though).
