Following a course that they suspect Amanda deliberately plotted, Callie, Nia, and Hal piece together some cryptic clues. But they find more questions than answers and quickly realize that before they can figure out what happened to Amanda—the girl who changed their lives—they'll need to solve the most important mystery of all: Who is Amanda Valentino?
