The second in [a:Sherrilyn Kenyon|4430|Sherrilyn Kenyon|http://photo.goodreads.com/authors/1190655675p2/4430.jpg]'s Dark Hunter series. Grace and Julian Alexander (from [b:Fantasy Lover|84136|Fantasy Lover (Dark-Hunter, #1)|Sherrilyn Kenyon|http://photo.goodreads.com/books/1171050604s/84136.jpg|2384]) make an appearance, but instead of hunky men coming out of books, this one has hunky men as not-vampires! Again with the crack-tastic-ness, but it was very enjoyable.

P.S. - I don't know why goodreads has it listed as the 4th book, but it's the 2nd full-length book in the series (there's one short novella-type story that comes in between, but it really doesn't seem to have anything to do with this world).
