Get us into a bookstore — especially one as conveniently located as the new Books a Million in downtown's Houston Pavilions development — and there go at least a couple of hours down the drain. With an entire wall of publications ranging from The Nation and Mojo to Guns & Ammo and Vanity Fair, Books a Million is a magazine lover's paradise. Better yet, the staff won't mind if you sit a spell and browse the periodicals (as long as it's not one that comes in a sealed wrapper, but there are plenty of those too), or if you take a couple over to the in-store coffee shop and read as you sip.
