I check these lists a few times a week. They are constantly updating so make sure you bookmark the pages so that you can come back to it later to get even more books. Hope this helps those looking for some books for their ereaders!
KINDLE: Make sure it says "free" before you accept it. And you can change it to whatever genre you'd like on the far left hand side. Here are a few genres to help you out. Just click on the genre of your choice:
CHILDREN'S (choose the age group on the left)
KEEP THIS BUMPED PLEASE!
***EDIT*** SOME OF THEM ARE JUST PREVIEWS OF A BOOK. MOST OF THEM AREN'T BUT YOU MIGHT COME ACROSS A FEW THAT ARE. JUST MAKE SURE YOU READ THE "PRODUCT DETAILS" SECTION AND IT WILL TELL YOU IF IT IS FULL LENGTH OR NOT. PLUS SOME ARE NOVELLAS WHICH ARE MEANT TO BE SHORT STORIES. I JUST RECOMMEND TO READ THE DETAILS CAREFULLY AND MAYBE READ A REVIEW OR 2. THE REVIEWERS WILL TELL YOU IF IT IS JUST A PREVIEW OF A DIFFERENT BOOK OR NOT. HOPE THIS HELPS!
