Talk about crazy eBook genres -- I started with Zombie novels; survive the apocalypse, rebuild society after the apocalypse, zombie break-outs through history -- you name it we got it. Then I was reading super-hero fiction that was surprisingly similar to the teen-angst magical powers; just replace the dark and brooding black outfits with capes and cowls. One totally mind-bending jumble of genres, however, is Ex-Heroes by Peter Clines.
Meet a whole bunch of super-heroes! Think they were useful before the zombie apocalypse? They seem to be the only thing standing between humanity and a really bad ending. We meet and learn the backstory of 5 or 6 varied heroes with great names like "Zzzap!" He has the power to make electricity! Very useful when the zimbos have shut down your generator. Anyways this LA-based group of heroes gathers a bunch of survivors at Paramount Studios and sets up a society. They fight off Zombies, LA Gangs, former LA Gangs turned Zombie and other heroes turned zombie.
This one is fun. I laughed out loud at how ridiculous the genre could get -- but the story telling is great and I was entertained.
