My boyfriend bought me a sony ereader last year. I was in love...but missing one thing. He recently bought me the eReader cover with light! Well, life is complete. I don't know what I did without this before now...yes I do...at night I was reading in the dark with a flashlight. hahah No more. I should have bought this cover ages ago. If you are an avid reader like me, and you read till all hours of the night and your spouse needs to sleep in darkness, you are gonna need this to go with your ereader. Great buy!!!
