This is the 5th book in a series I strongly recommend you read in order, both because of the personality development that takes place across the books, and because old, presumed solved, issues raise their ugly heads in later books and it won't be half as much fun. The first four are 'Dead Witch Walking', 'The Good, The Bad and The Undead', 'Every Which Way But Dead', 'A Fistful of Charms' and now, of course, 'For A Few Demons More'.
Rachel Morgan started out going 'on the run' in the first book and despite soon physically settling in one place, she's still running. She lives in a society where humans are frightened of tomatoes because a genetically modified strain killed many of 'us' off, thereby making every supernatural creature unable to hide in the mass of humanity anymore. So you have everything, vampires, demons, pixies, werewolves and so on - collectively known as 'Inderlanders'. Rachel is one too, because Witches aren't just talented or learned humans, they're as otherworldly as vampires and perhaps because they aren't as obvious, trusted the less for it.
Rachel started out as a kind of supernatural policewoman, a 'runner', making sure humans aren't preyed upon (unless they want to be) and generally trying to keep the supernatural species from each other's throats. I don't like giving away plot developments, so look away here if you've not read the first book - she quickly loses this job, and sets up on her own with a not-quite-vampire (she was born that way, and has to die to become a vampire), Ivy.
What drove me to write this review - apart from the fact that she's keeping me hooked into book 5 - is that the paperback edition I have says on the front 'action packed chicklit with a supernatural twist' - the Times. I could kick the person who wrote that in the knee. Chicklit? Yes, Rachel ends up with boyfriend troubles, but the books don't revolve around them, nor do they revolve around the fact that Ivy, apart from being her friend, partner and housemate (churchmate?), is gay and in love with Rachel. These books have created a now highly detailed alternative society, just slightly skewed from our own, and Rachel is trying to survive in it and keep the people she cares about alive. If that's chick-lit, then so was Lord of the Rings! (I exaggerate for effect, in case you're wondering).
They're adult books, because sex does come into it, but Harrison uses sex as just one part of the plot, not THE plot, as Laurell K Hamilton's later books began to do.
This book is darker than the previous four. Rachel has been constantly getting in over her head ever since the 1st book, but up until now she's managed to just about squeak her way out of everything that's happened. I can't tell you more without giving away the plot, but Harrison is deepening her characters, as she has done all the way along - and this book ends with a shock, for us and for Rachel. I can't wait for the next.
Comparisons are invidious, but we all do it. I think Jim Butcher's 'Dresden Files' are brilliant, and though his and Harrison's worlds are different, they are both in the same sub-genre - and no-one would call Butcher's books 'chick lit'! So if you went off Laurell K Hamilton because it became sex sex sex, Harrison is for you - she's a much more imaginative writer.
Also, if you like fantasy of any stripe, even if you've not tried 'set in the "present" day' fantasy, try 'Dead Witch Walking'. You won't be disappointed.
