Claire Perry knows a split second can change everything. It can be the difference between sticking a perfect landing or falling off the beam. It can be the difference between a really fun party or a totally messed up one. Or sometimes, as Claire finds out, it can even be the difference between life…or death. For Claire’s younger sister, Nellie, an elite gymnast who is “destined for gold,” things have always come easy. A split second is usually all it takes to capture the attention of a boy at a party, and the judges at a meet, or their critical father—everyone. Then one night, one decision, one split second—changes their world forever. The two sisters get into a car accident that leaves one of them with a traumatic brain injury. Now, the sisters will have to figure out what’s worth fighting for and what are the limits of guilt, forgiveness, and sisterhood. Memories will come crashing back and secrets will come to light—whether they’re ready for them…or not.
