No, I'm not being sarcastic (I quite often am, but not when it comes to my friends' writing). So you think you can write is the title of a romance writing competition. There's not long left to get your entry in, but if you do have something suitable it's probably worth a try as the top prize is a two book contract with Harlequin.
My grandma used to grow a rose called Harlequin. There isn't one of that variety in the photo, but it's a romantic image, don't you think?
