Sorry, but I'm not a fan. I started reading "children of time" earlier this year, but I never finished it. His writing style isn't for me, and I only read "service model" because I read some reviews that it wasn't a typical Tchaikovsky book. I liked it enough, but I don't think I'll be picking up any of his other books.

In my opinion too much world building with too little story. I get that you need more world building for the sentient spiders (though I wonder if it had to be that detailed), but the other story line also wasn't really grabbing my attention.
