Feeder by Patrick Weekes
My rating: 3 of 5 stars
The world building was a little weak, ditto the Tia Lake/Lake Foundation mythology (and the "gods exist until they're forgotten" was better done in Pratchet's Hogfather). On the other hand, the relationship between Lori and Ben was very sweet, and the Handler/Lori pairing was interesting. The members of the Nix seemd to be all one note until the end, and there's a Big Reveal that felt incongruous and unnecessary.
