So I will jump in with a couple of nominations.
Seven Japanese Tales
by Junchiro Tanizaki. Since this is supposedly an open category I assume that, as the title implies, a collection of shorter stories can be considered.
Tanizaki is one of my favorite authors, and this is a great book to be introduced to his writing.
Available as an ebook.
I would also like to nominate Feast of All Saints
by Anne Rice.
I am cheating a little here, I read this in April as the book of the month for the evening book club at my local library. With the sesquicentennial of the Civil War this year it is a timely read.
Available as ebook.
