And not to triple post (but I am

), but I'll go ahead and throw some category suggestions out:
-Mystery (this would be literary mystery, not necessarily something from the mystery genre but something that somehow relates to a mystery, and could even be a non-fiction with a mystery)
-Romance (the same as Mystery; I'm allergic to most 'popular' romance books but love a good literary drama book with a great romance in it)
-Melancholia (this would be a book either focusing on or with a heavy atmosphere of melancholy or ennui)
-Contemporary Cross Continental (I know I could've said intercontinental but I like the alliteration; this would be a contemporary book, from the last say 20, 30 or 40 years, that takes place on at least two continents and/or far-away islands/places)
-World Exploration (this would be a book focusing on some type of physical exploration, perhaps like an adventure or journey; I would've just called it 'Exploration' but I wanted to distinguish it so that it wouldn't be construed as inner self-exploration, and I also would prefer it to be Earth exploration and not sci-fi space/moon exploration)
If any of these appeal to anyone, let me know and I'll nominate it for my Summer nomination.
Edit-Thanks for the reply, Bookworm_Girl, and you also prevented me from the dreaded triple-posting, heh.
