There are several ways to enter this one, but the mandatory entry is that you subscribe to her RSS feed. Extra entries include liking her page on Facebook, following her on Twitter, or doing a blog post like I just did. But don't just take my word for it, jump over to her page and get in on this one before it's too late. You've only got a few more hours to go then it's all over.
Didn't make it in time? That's okay as she's got a lot of other giveaways you can get in on. And by signing up for the email updates or RSS feed, you'll make sure to get in on any others she'll have coming up in the future.
