I rank TKH's early Wolfwalker books highly, and I'm still enamoured of the world and characters she has created over the course of her series. I'm sorry to say, however, that I was very disappointed by Wolf in Night. Although the characters were interesting, they couldn't drive the novel without the help of a gripping plot, which was missing until near the end. Individual scenes carry the whole of TKH's talent for suspense, but they don't merge into a greater plot (not yet anyway - I'll have to wait for the next book). The focus is primarily on characters who haven't done anything significant yet. The suspense often seems out of place, written into scenes that don't merit the attention. I wanted more than vague insinuations about a new plague threat. I feel as though the book were an over-long introduction to a far more interesting story, one I can't access until the sequel comes out.
Most frustrating was the language itself, which was so saturated with similes that it actually distracted from what was going on. The similes were often trite, unneccessary, and/or absurd, e.g. "tension like bone". One, two, three sentences in a row would contain some comparison that was unnecessary and took what was originally a well-detailed description to a level of bizarre imagery. I love TKH's stories, but I wanted to go through this one with a red pen.
