Georgette Heyer! I have ALL of them!
Monophonic - I got bored with literature - for instance, I would read all the books shortlisted for some literary prize (Booker?) and find they were all pretentious and difficult to finish. I used to read books for a literary agent (which is fun, by the way) and there is a lot of pretentious crap out there. Maybe I got lazy in the search for something truly readable and deep. I like good writing - I remember one author who said he wrote sentences, wasn't concerned with plot so much, and his books were great. So Robert Barnard, for instance, writes really well, even though his books are just mysteries. He taught English literature in Finland or Norway or some cold place like that for years. He writes a good sentence.
I got some good ideas for new books to read from all your posts - it's hard to find a good book to read!
