Difficult choice, people. Any Romance novel ever qualifies. So do most Fantasy books. Bujold has some real doozies. But I am going to dedicate this post to Catherine Asaro, who may have written the only worth wile series of scifi/romance ever and has been rewarded with some real toe curlers.
Yikes.....
Just to be clear, the only ones of these I have bought are Ascendant Sun and The Ruby Dice. For the other I want to express my eternal gratitude to my local library.
