17-year-old Syd, no pronouns, is a baker at a queer-owned and serving café in Austin, the Proud Muffin. (I love that name) After an unexpected break-up with girlfriend W, a devastated Syd mixes up a batch of brownies that turn out to cause people who consume them to join Syd among the newly single. Once Syd realizes what happens, Harley, pronouns that switch between they and he as indicated on a button, is enlisted to get the couples back together.

Despite being heartbroken, Syd discovers an attraction to Harley, which, while probably reciprocated, is also complicated! The characters are lovable, but not so simple that they seem too perfect. That lovable but imperfect description goes for the other heart of the story, the bakery itself. The whole story is a non-mystery Tales of the City for the 21st century. I'd love to see it continue.

So you get a sense of what the book is like:

Biscotti are croutons that people put in their coffee. Coffee croutons.
