I love weird westerns and this is definately one of the strangest ones I have ever read. Old Gods, New Gods, Tricksters, The Mexican Cavalry, The United States Gov't, Witchcraft, flying cities, the Mayan Underworld and spiders the size of ponies all get thrown into the mix. This is truly one of the most imaginative books I've read this year and will be re-reading in the next few.
I can't really talk about the plot without giving away some major spoilers, but it is more than just a horror story. It is densely written, layered with meaning and the entire trilogy is handsomely resolved at the end and leaves room for the author to continue writing more stories set in this universe (and I hope she does.)
The reason it only gets 4 stars is it really slows down in middle of the third book as we spend far too much time waiting with some of the characters for the protagonist to get a move on. I actually liked the guy, but he is not the brightest character and I kept wishing he would just hurry up so I could get to the main blow-out at the end.
Also, for those of you not in the know, this trilogy does contain a m/m love story, more or less.
Those of you looking for a unique, dark (and it is very dark) and compelling romance may want to check this out.
