On reflection, I revised my rating down from 3 stars to 2.5. I found the story hard to get into but then it suddenly got going, a couple of chapters in and I started to enjoy it. However, the pace wasn't sustained and I ended up finding the whole thing patchy, overly long and tedious by the end (I found I was skim-reading the last 100 pages a bit just to get it finished and find out whodunnit and why). A shame, because I loved the original SH stories and hoped that this might be a series worth pursuing. I doubt that I'll bother with any more of them though.
