Pre-Book Sneak Peeks & Information
On August 16, 2019, in their Three Years of Choices Blogpost, PB teased an upcoming mystery book.
On August 21, 2019, PB confirmed in a reply to an Instagram comment that they did in fact have a mystery book in development.
On September 30, 2019, PB stated that this book is still in the early planning stages, but they teased that the current plot for the book is about a murder mystery focusing on investigating who is murdering an elite society in New York. They teased an "unlikely pair of crime-solvers", thereby hinting at a dual lead story like Most Wanted.
In the December 2019 Livestream, they announced that Andrew and Jennifer (The Royal Romance) are currently working on this book and that it is scheduled to release mid-2020.
They stated that while there are horror elements, it's not a horror book. They also heavily implied that the big bad will be a serial killer.
