Dead teenager Sal Singh was charged with the murder of his girlfriend, Andie Bell, five years ago – but not everyone in the town is convinced he did it, especially 16-year-old Pippa Fitz-Amobi.  

Pippa decides for her high school senior capstone project that she wants to look into the disappearance of Andie Bell, who is said to have last been seen by her little sister Becca on April 18th, 2014. As a childhood acquaintance, Pippa had always respected and liked Sal since he stood up to her bullies for her when they were younger. Sal’s younger brother Ravi disapproves of Pippa wanting to relook into the investigation, as it ended with Sal being found dead in the woods from an apparent suicide. After finding Sal’s phone and discovering messages asking for an alibi from Sal to his friends, Ravi decides to help Pippa with the new investigation. As she dives deeper into the investigation with the help of Ravi, Pippa starts to discover hidden dark secrets about each party involved. For instance, Andie was seeing an older man, the reason why Sal’s friends wouldn’t offer an alibi for him, the last text to Andie from Sal that leaves the final moments of their relationship in question, and Sal’s “confession” to Andie’s murder that was shown to be sent after he died to his father. It leaves the reader thinking, “what else hasn’t been uncovered?” 

As the story continues and more secrets come to light, Pippa discovers she’s in danger. Her enemies lurking through the shadows and those involved in the disappearance remaining silent, it’s up to Pippa to get to the bottom of Andie’s disappearance and Sal’s death while also watching her own back. Everyone is a suspect, and both blood and water are very thick.
