I sort of see where you're coming from about Pratchett,
Nog; he's a bit of an acquired taste, but I've found he gets better with age (as long as he still manages to battle Alzheimer's, at least
). You might like to try The Wee Free Men and A Hat Full of Sky, if you haven't yet - there's a poet's heart beating in these. If you like them, anything else with Granny Weatherwax in it - that woman rocks!
