Cake is inspired on the book The Night Circus by Erin Morgenstern.
Synopsis: The circus arrives without warning. No announcements precede it. It is simply there, when yesterday it was not. Within the black-and-white striped canvas tents is an utterly unique experience full of breathtaking amazements. It is called Le Cirque des Rêves, and it is only open at night.

But behind the scenes, a fierce competition is underway: a duel between two young magicians, Celia and Marco, who have been trained since childhood expressly for this purpose by their mercurial instructors. Unbeknownst to them both, this is a game in which only one can be left standing. Despite the high stakes, Celia and Marco soon tumble headfirst into love, setting off a domino effect of dangerous consequences, and leaving the lives of everyone, from the performers to the patrons, hanging in the balance.

The contortionist is who I decided to highlight in the tent on the bottom tier.
The I added the steampunk look because of the everchanging circus that always travels & opens only at night.
The topper is based upon the love for the two young magicians that are initially supposed to not become friend, but end up falling in love.
