Cover blurb: It's February 14th and Owen is a no-show for Toshiko's not-Valentine's-Valentine's Night at the opera.
Worse, when Ianto turns up he has bad news for Toshiko, for Cardiff and for fans of classical music — the opera is full of aliens. The doors are bolted, there's no way out, and this could be the final curtain.
