I used to be famous among my friends and family for eclectic book tastes. I could happily read teenage romantic fiction, follow it up with a few good vampire reads then move onto something fairly classic, take a break with a good crime story then get my brain engaged with the latest hot new literary book. You get the picture.
When I ws pregnant and had just had DS I was too tired to read anything that required a brain. I reverted to vampire and werewolves only. And even then, mostly I just watched bad tv. Then I came back to work and I found that actually, I could read on the train and I also was a little more engaged. So I started reading a few books that were recommended by friends - nothing too hardcore but you know "good" fiction, in between the vampires and werewolves 
But... now that I thought I was up for more, I find I'm not. I wanted to read some post apocolypse stuff which I've always loved, but the thought of all those children dying destroys me. so I thought I'd try a good crime drama, but the one I picked started with a woman being tortured and I found I just couldn't carry on. So then I thought, sod this, I'll go for crappy teenage stuff but all I could think was, "for pete's sake, this is so unrealistic."
I'm doomed. I love reading. But this level of emotion is not helping!
