There is no shame in liking Fiona, even if it took a while for you to warm up to her ;). It doesn't surprise me you like Sullen Girl considering you also like her rendition of Across the Universe. You may like Never is a Promise and The Child is Gone as well, I find they get along well with Sullen Girl.
Well I'm glad it's gotten better in real life! Yeah, I got my book a while ago, but I haven't read it yet. I hope to see you around more, but if not, I'll bug you on GoodReads. :)
