Please, tell me all your thoughts on Heyer's romances.

[kassia06]

For my final assignment in my databases class, I'm making a database of Heyer romances. The idea behind it is that a user could search for books with a certain type of hero or heroine, or remind themselves which book is Black Sheep and which is Lady of Quality, or figure out which Heyer book to recommend to a friend who didn't like Sylvester but liked Venetia. It will include reader reviews, favorites, and least-favorites. No one will be seeing this information but my teacher, and in theory I could make it all up, but that's no fun.

Anyway, if you're reading this and you're in the mood to rhapsodize about Georgette Heyer, or you're in the mood to complain about how much of a jerk Sherry in Friday's Child is, please take a second to tell me some of your thoughts. You can just tell me your favorite book, or you can write a whole essay -- all information is good! I'm interested in hearing:

Favorite book(s): (feel free to add an estimate of how many times you've read 'em, if you can guess)
Least favorite book(s):
Favorite character(s):
Least favorite character(s):
Are there any Heyer books you liked at first but liked less on rereading? Any books you didn't like at first that have really grown on you?
And, for a bonus, which books do you get mixed up? I always get The Quiet Gentleman and Unknown Ajax confused.

Thanks so much!
