After a tragic accident ends her best friend's life, 17-year-old Becca Thompson succumbs to grief the only way she knows how: by wallowing in it. She's a fragment of the person she once was-far too broken to enjoy the summer before her senior year. But when Ben McCain, her best friend's older brother, returns home, Becca must face her new reality head on.

She isn't interested in Ben's games, especially since he abandoned his sister during the months leading up to her death. But when he begs for her help in uncovering the truth about what really happened the night of his sister's death, Becca finds herself agreeing, hoping to clear up rumors swirling in the wake of her best friend's accident.

An unhinged ex-boyfriend, secret bucket lists, and garage parties in the place Becca calls home soon lead her to the answers she's so desperate to unveil. But nobody is being honest, not even Ben. And the closer Becca gets to the truth-and to Ben-the more danger seems to surround her.

Clearing her best friend's name was all she wanted to do, but Becca is quickly realizing that the truth she craves might be uglier than the lies her best friend kept.
