I have ::always:: loved Pride and Prejudice - that will always win my vote!
I did just finish a (new to me) book that I ::loved:: called:
Juliet by Anne Fortier
(it's a historical fiction that ties back with the original Romeo and Juliet - and supposedly the characters that inspired Shakesphere - it goes back and forth from the year of 1340 to present day and it all tied together, had a bit a of mystery, romance and Indiana Jones feeling to it. Great fun!)
