So when her wayward sister Riley shows up in the middle of the night, covered in blood with a dead body riding shotgun, everything Beck has worked for is put at risk. She doesn’t know if she can even trust Riley, who has a Ph.D. in deception. When a detective arrives to question them, Beck is relieved…right up to the moment he tries to kill them both, revealing that there is a much darker conspiracy in motion. The sisters’ only hope is to heal their fractured relationship and work together. In doing so, they uncover a connection between their dangerous present and troubled past, back to the very reason their mother abandoned them.
