Ronnie Campbell thinks she's handling her sister Katherine's suicide just fine. Grade 10 has started and while there are lots of whispered rumors in the hall, Ronnie tries to ignore them. But it's hard living in the shadow of a dead girl, especially one who had it all: popularity, good looks and a promising future. Even though she tries to hide it, Ronnie is lost and struggles to find out why her seemingly perfect sister would take such a drastic step. As she searches for answers, Ronnie continues to see and speak to Katherine as if she were still alive. But no amount of imaginary conversations can tell Ronnie what pushed her sister to the edge. All she has is a strip of photo booth images of Katherine with an unknown boy-the person who might just hold the key to everything. While Ronnie denies her grief, the power of her emotions threatens to destroy her.
