if you want something good to read this summer, i recommend this book. the premise is, a woman wakes up each morning with no memory of the recent past. she can remember things from long ago, but anything within the last few years is gone. she can remember what happens during each day, but when she goes to sleep at night, she loses it all.
she finds a journal that she has been keeping in her closet, and the more she reads, the more terrifying the truth of her situation becomes.
very well written. they're making a movie out of it. if you're looking for a good read, here it is.
