Spectacular - A lack of excitement?

I follow Stephanie Garber on Instagram and did not realize Spectacular came out this week! Are people picking this one up? If you've read it, what were your thoughts?

I've read all her books, and ACFTL left me feeling like it was a set up for another series and not the conclusion of a series. When Spectacular was first announced, there was a general feeling that there was not a need for more in the Caraval universe. I didn't see as much promotion or hype for this one - or was I just living under a rock?
