Felicity Koerber is finally getting her life together. She has a fiancé, her bean to bar chocolate shop on Galveston's historic Strand has become a gathering spot for the community, and she is ready to embrace whatever the future holds. She's ready for another launch party - despite the disaster at her grand opening, when she'd first gotten involved with solving a murder. And this time she's embracing her status as a sleuth. She's hosting a murder mystery weekend to celebrate the new Mystery Flavor line of craft chocolate bars. She's held a contest to choose the attendees, who will all stay at her aunt's flip hotel and enjoy the island. It's all supposed to be perfectly random - only, Felicity starts to uncover connections between her guests. When one of them winds up murdered, Felicity has to keep her aunt from becoming the main suspect. The killer is very clearly calling Felicity out, leaving clues that mean little to anyone other than her. But that doesn't narrow down the suspect pool. Her guests are there because they love the true crime podcast she's been featured on. And she can't decide whether the killer wants her to catch them - or just wants to taunt her. Meanwhile, Felicity is also playing host to her future in-laws and discovers that her fiancé's sister, who is also a cop, is very competitive. Can Felicity hold her own and make a good impression, while keeping her business together and her aunt out of jail? And can Felicity solve it in time to protect the people she cares about from becoming additional victims?
