Current YA seems to be full of girls who can't remember who they are. Or perhaps if they can remember who they are, they don't remember the past five years, or five weeks, or five hours. Usually, someone is trying to kill them, and the clue to who and why lies in the lost memories.
After reading The Testing and The Program in quick succession, I realized that amnesia is a pretty huge topic right now in YA fiction. I can see the appeal - it adds automatic suspense and a sense of the mysterious. At the same time, it can be a bit of a cheat (memories come rushing back and all problems are solved!), and it often leads to a disappointing reveal.
Below are just a smattering of titles published within the last twelve months, plus a few upcoming ones we'll get later in 2013. I think it's pretty remarkable there are so many in just a little over a calendar year. If I extended the date range to two or three years, there'd be even more (such as Cat Patrick's Forgotten or Elizabeth Scott's As I Wake). So many! Descriptions come from Worldcat.
