If I'm not feeling well, one of the ways I know that I'm getting sick is that I don't want to do anything... and unfortunately, that includes reading. I tend to sleep when I get sick... and don't even get me started on migraines. There's no way I'm reading then.
However, I was recovering from the flu several years ago (the only time I've ever had it and, Lord willing, I never want it again!) and my husband brought a book for me. I was still weak and reading was about all I could do (there was only so much television I could watch). It was Karin Slaughter's first book Blindsighted and she's still one of my favorites (even though I took a hiatus from her after Beyond Reach came out...I eventually forgave her).
What about you?
