Initial thoughts: I felt... underwhelmed. Yes, that's the word, underwhelmed.
Blue Lily, Lily Blue didn't hold my attention as well as the first two books. I partly peg this to the fact that I didn't have that much time to read over the past two weeks. But when I did have time, I wasn't entirely looking forward to continuing with this book either. It was decidedly slow and for the first 55% of the book, there was no semblance of direction. It was like being stuck in a labyrinth with no way out, and not the kind of fun labyrinth you voluntarily signed up for during a funfair of sorts.
The first half of the book basically let me down. I was bored and had half a mind to give up. But I had unanswered questions from the first two books to which I wanted answers. Instead of unfurling, they just became foggier. I'm glad I know how the book ended and I will continue with
The Raven King when it comes out but part of me thinks I should've just read a spoiler-induced summary, so I won't be lost when I read the final book in the series.
In any case, Maggie Stiefvater's prose continued to be beautiful. That really was the saving grace of
Blue Lily, Lily Blue for me.
