What I liked: The 1st book was terrific. The trilogy's concept/world was refreshingly unique. Writing quality was superior to other YA. Holland's backstory is great!
What I Didn't Like: The mystery of Kell & Lila's origin just gets blown over. The reveal of why Alucard left lacks punch b/c it's told twice. We never find out what happens to White London, Ned's story seems pointless, Kell/Rhy's bond is basically insignificant.
