I'd do nothing but reading if I could (ok, maybe eat some great food, buy some fancy shoes between two books...oh, and spend some quality time with the gorgeous guy I married while I am on reading-break anyway...)
Watching Teen Wolf season 3 (yes, the complete season 3, which means 24 episodes), because I just discovered that I can watch TV on my laptop and with Amazon prime I can stream a lot of stuff for free.
And why Teen Wolf? Two Words. Derek Hale.
