Nightlife tells the story of two brothers. Cal - the younger brother who is half human / half 'monster' and Niko the older brother who will do whatever it takes to protect his sibling from the creatures that constantly pursue them.
The story is told by Cal the younger brother, who makes for a cynical protagonist, with an extremely cutting sense of humour. It's interesting how when the style of narration changes (Cal undergoes something of a transformation halfway through) that underlying humour is still there, albeit with a much nastier twist.
It does take a couple of chapters for the story to get going, but almost without realising it, you are slowly drawn into Cal and Niko's world. And once you are in there it becomes very hard to put the book down. Although the major focus of the story is the relationship between the two brothers and their struggle to survive, the world is populated with interesting and original secondary characters - Boggy, Georgina, Robin Goodfellow (yes, that Robin Goodfellow :) ), Promise and Abbagor. It's made very clear that these are creatures / people who all have their own agendas and problems to deal with and who don't necessarily have the welfare of the brothers at heart. It's refreshing not to have the good guys and the bad guys made completely obvious.
Because there is a major change in protagonist behaviour halfway through, this is a book of two halves. The change is very much a necessary part of the plot, but I did prefer the narration of the first half more, finding that because there was less interaction with other characters in the second half it did get slightly bogged down in exposition.
Having said that I recommend this book for anyone who's looking for something a little different in the Urban Fantasy line. (Definitely worth checking out if you like the Ukiah Oregon series by Wen Spencer.)
Moonshine the second book in the series is also available.
