An unusual read, I loved the first person narrative that switched between the two main characters, letting the reader inside their innermost thoughts. The interspersed lists of ten were also an interesting touch. I had never come across synesthesia before so I found that very intriguing (and confusing to begin with, not realising it was actually a thing!)
Having just finished reading this, I'm not quite sure how I feel about it however. So many unanswered questions. Whilst it is definitely a novel that will stay with me, I found the end deeply unsatisfying. Like an inferior firework. All that amazing build-up then pffffttt... Hmmm. Not that I need every loose end wrapped up in a story but I was definitely left wanting more here.
