Reading physical books whilst cosleeping?

I cosleep with my nearly 1 year old and have recently gotten back into reading. I do use ebooks but prefer physical books and sometimes that's all I can get from the library. I'm looking for tips on how to best read my book when my wee one is asleep but I'm not quite ready to sleep yet. Please tell me someone has found an amazing book light or has some other genius tip I don't know yet.
