Love, Death, Robots, and Zombies — Tom O'Donnell

A century after the apocalypse, three factions vie for the scraps of a blighted world: a race of sentient machines, a mindless horde of undead, and the faltering remnants of humanity.

Living with his robotic dog in the crumbling library of a dead city, fifteen-year-old Tristan just wants to be left alone. When Echo, a childhood friend, draws him into a violent clash, however, the two of them are forced to flee into the wastes with a roving army on their heels.

Their goal: a distant Utopian enclave. Their route: a hazardous path through the zombified ruins of once-great cites, deep into territory held by sentient robots. Along the way, Tristan's feelings for Echo grow--but does she genuinely reciprocate, or is she only doing what's necessary to survive? Can they find a measure of peace together in the hostile ruins of a dead civilization, or is even the enclave just another lie?

Love, Death, Robots, and Zombies takes three sci-fi cliches (robots, zombies, and the apocalypse), mashes them together, embraces them, and ends up more entertaining than it has any right to be.
