My own unapologetic opinions on books and writing.
by Ben Aaronovitch
The stories in this series have a way of building on the established world, but always adding something new. This one nearly lost me when the nature of a peripheral character started to sound too much like it was borrowing from the teenage Paranormal Romance genre, but it recovered nicely and turned out to be one of the best in the series so far.
A new adventure for Peter Grant takes him underground, well, to the London Underground where tales of sewer creatures and secret tunnels always provide plenty of scope to extrapolate a good story setting. Watching this character develop along with his magical abilities is definitely one of the strengths of the series.
Magic, supernatural creatures and superior officers who don't want to know are all part of the job, right?
Anything else I can say will give spoilers, so I'll just move on to the next one in the series and simply say, this was good.
