As you may or may not know, Amazon often offers free kindle books, for promotion or such.
You don't have to have a Kindle to enjoy such awesome goodies either, there are several different apps you can download, just click here
The prices of these books change really quickly, and they're sometimes only free for one day before returning to previous price.
Currently free books, that I'd like to mention are:
Heavenly by Jennifer Laurens
The Emerald Talisman by Brenda Pandos
Demon Girl by Penelope Fletcher
Starfire Angels by Melanie Nilles
Hollowland by Amanda Hocking
Zombies don't cry by Rusty Fischer
^^^Just to name a few, there are so many more on Amazon, and the lists and prices are updated all the time.
so Quick! grab these books before they're gone!
