Almost finished with Gaiman's Neverwhere. Superb book.
Any recommendations for another good Gaiman?
I'm right in the middle of "American Gods" by him and am really enjoying it. I've also read "Good Omens" that he co-wrote with Terry Pratchett which was a humorous look at the appocolypse. It has sort of a Douglas Adam's feel to it so if you read and enjoyed "Hitchhiker's Guide..." then youll enjoy it.
Finished American Gods a couple of weeks ago and haven't had time since to start up a new book due to remodeling tasks. Loved that book and would highly recommend it and will definitely be looking up some of his other books.

Just got Angels and Visitations from the library today.
I enjoyed Neverwhere more than American Gods. My favorite from Gaiman is Anansi Boys.
Anansi Boys? Really? Interesting. It was my least favorite...easily. American Gods, then Sandman, then Neverwhere with Anansi Boys a distant 4th from what I've read. Maybe I missed something. But the plot was "my 'brother' is annoying and stealing my girlfriend...I need to risk everything in the world to get rid of him". No urgency, no tension. Just goofy witches and a tale of "inner self". Maybe I didn't read close enough though...
I have to qualify this by saying this is one of my Audio books reads and the narrator was excellent. I'm sure part of my enjoyment came from that. The surface plot was my dad just died and I just found out he is ancient African god. I also just found out I have an uber-cool brother who does everything great and is stealing my girlfriend and I'm such a spineless loser that I can't possibly do anything about it.
The story was about strength of character, confidence, true love, and ultimately about family. It's also about looking deeper than whats on the surface to see the true story.
On the surface its Fat Charlie + Spider = Anansi, so what traits one has the other must be lacking. As the story progresses and the characters develop we realize that even though these brothers look like opposites they aren't. Is Fat Charlie really that pathetic? Is Spider really that confident?
And even though Anansi died at the start, you really get to know him and love him. I loved the folk tales, old world and new.
I think the depth of the characters is what really made this a great book for me. Gaiman helps you see the good in all his characters while making sure they can be very annoying at times.
I was never any good at book reviews so this may not be such a ringing endorsement, but for me it is so far the best work from one of my top ten favorite authors.
