It's rare that I come across a book-review or -recommendation site that fills me with joy, but Flashlight Worthy absolutely does. Their choices are thoughtful and interesting and the lists into which they're grouped are useful and fun.
A few that jumped out at me:
Great Books About Magicians and Circuses
Culinary Memoirs That Make Perfect Beach Reads
Favorite Reissues of Neglected Books
Creepy Houses That Must Be Explored
The Chocolate and Peanut Butter of Noir and Speculative Fiction
A Practical Fiction List for Surviving After the Apocalypse
The Queens' P.O.V.: Books About How Henry VIII Got Past First Base
Their twitter feed looks like a gem too. Now I'm triple-craving a week by myself in a cabin on an island in the middle of a lake with towering piles of books and firewood.
