As I sat at my desk, writing blissfully away about iPad apps - or was it tips for getting into shape for the summer? - my phone rang.
It was my friend the former punk rocker.
"Sarah Waters was here and I hugged her and gave her a book!" she said breathlessly into the phone. "I feel like one of those crazy fans."
It turns out that the author of one of my favorite books, Fingersmith, was in town for a special reading at Kulturhuset, and the former punk rocker's daughter not only went, she managed to get a 45-minute private interview with Waters for her blog Bookleaf.se. And of course she mentioned that she works at the Science Fiction Book Shop and that Waters should really check it out.
So my friend the former punk rocker, who is one of the managers there, wasn't completely surprised to see Sarah Waters wander into the store. But she did lose her cool - but only in the best way, all gushing and full of admiration.
"I'm a huge fan of yours," she told Sarah. "And I know you haven't read this and I think you'd like it, it's by John Ajvide Lindqvist, it's Let the Right One In. It's a present from me because you've given me so much because I love all of your books."
Sarah apparently is very kind and gracious and is completely unruffled by gushing fans.
"And you're the one who turned me on to her, " the former punk rocker said to me. "So I just had to tell you!"
I only wish that I had been there to gush, too.
The Swedish phrase for the day is förtjust i, which means to have a crush on.
