I loved this book! I think it's the best from this pair of authors so far. It has the adventuring and crazy music of Nick & Norah coupled with the warm friendships and eclectic supporting characters of Naomi & Eli. I loved that Dash was 'snarly' and Lily was 'shrilly' rather than being too cool hipsters- after all, it's now game over for hipsters, right?
I'm so glad I read this book this week as it's almost the same time of year as the setting.
Finally, I loved this book because I have ALWAYS wanted to find a hidden message in a bookshop.
