When it comes to reading the titles and cover blurbs of SF/fantasy books, I am with Timothy Burke:
Other things that are likely to drive me off:
1) “Book One in the Dark Swords of Black Terror Trilogy”.
2) Mostly, if the word “vampire” appears anywhere in the cover, title or blurb. It stops being “mostly” if “vampire” appears in the same blurb with “elf”.
3) Titles or blurbs that contain the name of a fantasy kingdom that sounds more like a prescription medicine for depression or impotence.
4) Anything that contains three of the following four elements in the blurb: plucky but innocent young heroine, farmboy with a destiny, dark lord of evil, wise ancient wizard. “Handsome voodoo priest” is a bonus demerit.
5) The word, “Drizzt”.
