the rest of the Pratchetts

Reaper man.  This book had a very early feel-- you could tell the author was still working on developing the character, like Granny Weatherwax in Equal rites. 
This one was a little less comical and a little more insightful than most, but certainly not one of his best.

Small gods.  This one is going on my list with Dogma and Good omens.  They can make you think about religions in a way no serious media ever could: it doesn't really discuss, or compare, or judge, or promote.  It's just a story.  In the way The passion is just a story.  Besides the plot, there is no actual theme, no argument, so you can go wherever you fancy.  On your own, without being led.  Or hearded, depending on which type of hairy little herded animal you are.  "Sheep are stupid and have to be herded.  But goats are intelligent and want to be led."

Sourcery.  This is one of the books in which we feel the authors awareness of darkeness.  He's not being mean or scary, but he knows that other people can be. 
It was also very funny, though.

Soul music.  This one had small elements of religion but focused mainly on Rock & Roll.  I especially appreciated the social commentary as well as the focus on the power of music, almost as something primal. 

Thief of time.  Read Pratchett.  Read for entertainment, read for the irreverence the books contain, and read for the wisdom.

Truckers.  This is one of the author's books strictly for younger audiences.  Still, he showed his usual amount of imagination.  His style was easy but not dull and the story flowed smoothly, with a commendable amount of suspense.

I believe there are more to this series, but even with access to three library systems, I can't get my hands on the others right now.

Truth.  I've almost waited too long to do this review properly.  As always, the story was more entertaining than anything else, but it had some little nuggets of wisdom regarding the nature of truth and free speech.  Read it.

The Wee Free Men.  I can't think of a non-Pratchett book that could hope to compare with this one; it even surpasses some of his other Discworld books.  The Wee Fee Men (with or without italics) is and are hilarious.  I enjoy this author's books because they are always funny, throw out a few things to make you think, and havve good plot and character development.  Rock on.

Witches abroad.  This book uses a few of the characters, as well as the general witch-network set up, that the author used in The Wee Free Men and A hat full of sky.  His style and characters were what I have come to expect from him.  It was a book leaning more towards preteen readers, but I enjoyed it anyway.

Wyrd sisters.  This one might come before Witches abroad (I can't remember) and sets up the Coven sub-series (as I think of it).  It's kind of blending in to the background of the whole universe-- this book doesn't jump out and claim a place for itself.
