Interesting but ultimately disappointing.
My first impression was bad (a glossary… the next worse thing is a freaking map), but it livened up once I got used the author’s rhythmn. One character in particular kept in interested (Horvil, happy-go-lucky geek, a laugh a minute), while others where a tiny bit one-dimensional.
But, the story just fails to deliver. Plots fall over, a major plot is obviously a device left for the sequel, and the entire book reads as if the author simply ran out of space (or the editor said “enough!” and it was all bumped into another novel).
Single word review – Average.
