When Koby Hill and Keaton Rutledge were orphaned at age two, they were separated, but their unbreakable connection lingered. Years later, they reunite and decide to make up for lost time and capitalize on their shared interests by opening up a well-stocked bookstore and cozy soul-food café in the quaint Pacific Northwest town of Timber Lake. But this new chapter of their lives could end on a cliffhanger after Koby's foster brother is found murdered.

The murder, which occurred in public between light-rail stops, seems impossible for the police to solve. But as Keaton and Koby know, two heads are always better than one, especially when it comes to mysteries. With just a week to go before the grand opening of their new café, the twins will use their revitalized connection with each other to make sure this is the killer's final page.
