This one took me a while to get into, but once I did it was amazing. Beau is a bratty, selfish man child, and he's always been judgmental of his dad's club. Emerson is marrying Beau's ex-girlfriend, which Beau is still really weirded out by.
Maggie has helped run Salacious since it's start, but she's never really been inside the club for herself. When a gathering with the girls leads to her taking the Salacious kink test, she's in for a big surprise. When Beau's friends convince him to take it, too, he's also in for a big shock.
They end up meeting up through the App, but go on masquerade night and into a dark room so they can't see one another, but that only lasts for so long. After that, they not only grapple with what the people around them will think, but their own versions of what they see.
