This is book 8 of a series involving a Druid that always is involved in some sort of trouble. In this case, he is fighting a war against the vampires.
Every time I read one of these books I realize how awesome druids can be, although I unfortunately tend to forget after awhile.
These books are amusing and easy to read. The dramatic scenes are also entertaining.
