If you’re a mash-up fan you might be interested in Simon & Schuster’s paperback release of The War of the Worlds, Plus Blood, Guts and Zombies by Eric S. Brown.
Description: The invasion begins … and the dead start to rise. There’s panic in the streets of London as invaders from Mars wreak havoc on the living, slaying the populace with Heat-Rays and poisonous clouds of black smoke. Humanity struggles to survive against technology far beyond its own, meeting fear and death at every turn. But that’s not the only struggle mankind must face. The dead are rising from their graves with an insatiable hunger for human flesh. Friends, neighbors and loved ones lost to the war of the worlds are now the enemy and the Earth is forever changed. It’s kill or be killed, if you want to survive, otherwise you might become one of the walking dead yourself.
