It took me a while to pick up this series, and I admit that I expected to be impressed. I'm not sure it quite lived up to those expectations, but it was an entertaining read none-the-less. I enjoyed the plot overall, though sometimes the tension waned. I also found Harry to be a bit annoying, but he sort of grew on me by the end. I really liked the interactions between him and Karrin Murphy (This is mainly what kept me reading). 
 I'll likely give the next few books a shot before deciding whether or not the series is worthwhile.
