It was Seduced by Moonlight. I had bought a Caress of Twilight, read it through in a day, and spent months and months foaming at the mouth to find out what happens when Merry visits the Seelie Court. When Seduced by Moonlight came out, I was broke, but wait! I have a library card. I put it on hold, but I'm 18th in line, or something. So I have to foam at the mouth some more. Finally, it comes in, I race to the library and grab it. And race home to shut myself in my room and FIND OUT WHAT HAPPENS!!!

And they never even get there. I could have cried.
