Eight years ago, camp counselor Bella Estes stormed out of a late night party, angry and intoxicated. By morning she was dead--her bunkmate Mackenzie Reed the main suspect. Lake Eklutna keeps a cold grip on its icy secrets. Who really killed Bella and why did Mack's girlfriend refuse to alibi her the night Bella drowned? New evidence casts doubt on everything Mack and Celeste thought they knew about Bella, their shared past, and the summer retreat now known as Camp Murder. With the killer still free, can Mack and Celeste mend their fractured relationship? Or will the secrets of the lake draw them into further danger?.
