Cassidy "Cazz" Warner, a smart, sporty, reticent newcomer to the senior class at Claiborne High, unwittingly attracts the attention of its most popular girl: Sarah Perkins, a bright, athletic, charismatic beauty. Just as the two begin to understand how extraordinary their friendship is, another cross-country move wrests Cazz away.
Ten years later, Cazz unexpectedly runs into Sarah during a fraud investigation at Sarah's charitable foundation. The women are inexorably drawn to each other, but Cazz's investigation into the foundation's finances limits her ability to be entirely honest with Sarah.
Already wary of Cazz for not keeping in touch after Claiborne, Sarah demands the truth. Will Cazz own up to her feelings for Sarah? Or is she too late? And will Cazz's investigation bring a killer to justice, or will she sacrifice herself to protect Sarah from a man desperate to conceal his crimes?
