"If you find a book you love, do you hunt down other books by the same author?"
If the book is a super delight, of course I hunt down the author in all other forms. That isn't to say I read the other books with a blind eye. I have started into some author's other books and realized the genius was a one time thing. Some authors just seem to write in a style and along storylines that continue to please. Although, admittedly, this is really rare to find especially with the current trend taking books a bit out of my comfort zone. Plus, some authors seem to get a bit to high in the instep and their books start to show a love of something other than the story and its characters.
On the opposite side of the coin there have been a few authors I have given another chance after blacklisting them. This isn't always a good experience but sometimes I have found some winners.
