by far one of the best written series ive read would have to be E.E.Knight's Vampire Earth saga. set in a post apocalyptic setting where vampires have taken over and enslaved the human race save for a human resistance made up of humans trained by these other creatures that oppose the vampires creating a three caste system of wolves, cats, and bears to fight the onslaught. the first book is titles way of the wolf and the series follows one, david valentine as he starts his wolf training and ends with him as a bear in the 8th book, all the while showing off his journeys throughout the ravaged american countrysides and his battles.
