The Brimstone Deception

Lisa Shearin brings us pleasant urban fantasy in The Brimstone Deception, book 3 of the SPI Files series.  The premise of her series is that creatures of fantasy are real it's just that people can’t see them and, when they do encounter them, rationalize it away.  Because creatures of fantasy can be quite evil with plots to bring about certain doom there needs to be a police force that guards against them.  Our heroine is a human member of just such a police force.  A seer, she is able to see past spells and glamour so she knows what’s what and who’s who.  In this book a drug is being pushed that allows everyday humans to see past glamours as well, which naturally drives them crazy.  The SPI agency starts after the drug business only to find that it is just the tip of the iceberg.   Although it is the third of the series it can be read alone.  

All in all a book/series I would recommend to lovers of the genre.
