Romantic Historical Fiction Lovers discussion

Hi Everyone!
I have once more decided to drop the gauntlet for a new RHF reading challenge with the chance to win a book up to $20.00 from The Book Depository (free worldwide shipping).
The rules are simple:
Read and review one book from each of our group book shelves by the end of this year to be eligible for the drawing.
If more than 10 people complete the challenge, I will draw two winners from the group.
Good luck and happy reading!

I just want to clarify. To be eligible you must read one book from each of the 37 bookshelves? If this is not correct which bookshelves are we to use and how many are there. I am always up for a challenge but 37 is WAY too ambitious for me when I am already participating in other challenges and my monthly library book group.
