This is a great Giles/Wes story in which Giles gets a birthday gift he never expected.
The summary says "Wesley visits Giles on his birthday to discuss the reappearance of Faith and reveals a secret or two of his own."
I have to say I really love the way Raynedancer writes these two characters and it's certainly a good way of warming oneself up on a cold Saturday afternoon. :)
