Until, on the tenth anniversary of Sara's death, she receives a letter that makes the past impossible to ignore. Kat realizes that going back to Liberty, Louisiana, might be the only way to move forward and find some peace. And there is a killer out there who was never caught. With plenty of enemies, no one to trust and a killer determined to keep a dark secret buried, Kat must decide if justice is worth fighting, and dying, for.
