On my way to the bookstore...

I'm not trying to be snarky, but the bookstore probably has a display of what's new - and what might be interesting to you is hard to guess.

And since I freely admit that I am hopelessly, eternally stuck in what's old and interesting I am probably not the best person to get the ball rolling in answering your question. I just happened to be the first to show up. Good luck. Just getting in the bookstore door is always enough to justify the trip.

Oh come now. There's that new Fagles Aeneid, that's supposed to be something.

If you're going to a Barnes and Noble type place, it's always good to go through the "remainders", and the big cheap book displays. Discounted books. i got a Francine Prose novel that I wanted to read for less than $5$, hardcover.
i assume if you're posting here that you love books, so...
what do you like to read?
I, personally, try to buy hardcovers as much as possible, because I have thousands of books and they are pleasing because of the hard spines.
Books are Books. You should go in and be, sort of, a bookaphile. Touch the books, handle them, look for the publishing stats, read the author profile, walk away. Return to the books that delight you with descriptions that resonate with you.
What do you want to read? This is an excellent forum for reccomendations - just be specific.
Good luck and happy trails!

Give yourself plenty of time to browse. One of the better things about small bookstores is that they often tag interesting books with a short synopsis or review by a member of the staff. Take a list, so you don't draw a blank about trying to find a book you've heard about. Get a fiction title, a non-fiction title, a graphic novel and then a classic you've always meant to read. If you're having trouble deciding, pick a book that looks, feels and smells good.
Enjoy.
