This is the series of novels that the Night Watch and Day Watch movies are based on. If you haven’t seen them you should, Russian or not they are pretty cool. The books follow the Moscow branches of the Night Watch and Day Watch made up of ‘others’. The Others are people with special abilities, sorcerers, witches vampires etc. They have been involved in a battle of good and evil for centuries, although a truce currently exists at the moment. This is simply to stop outright war between them destroying the world. The truce is monitored by the Watches, the Night Watch , made up of good others, police the evil others and the Day Watch made up of evil others, police the good others. Stopping each other from either wrecking havoc amongst the normal people or even doing to much good.
The series is told in about 3 stand alone tales in each book with an over arcing plot culminating in a showdown in Edinburgh where most of the forth and final book is set.
I really recommend the series, especially if you enjoyed the movies.
