Apocalypse Monkey: The More I Court Death, the Stronger I Get

Looking for an Apocalyptic Novel with a Wild Premise That Still Feels Realistic

Looking for books similar to The Sorrow of the Night. It's a wildly imaginative novel: Russia and Ukraine join forces to fight the EU, while the U.S. president nearly starves to death in an apocalyptic bunker. The male lead is tricked into going to Japan for illegal work, but the whole country is already overrun with zombies. Please recommend something similar.
