Camp Clearwater is home to best friends Nate, Owen and Mercy. They practically grew up on the Starling River. But the summer they turn sixteen an incident forces the camp to close its doors. Mike Elliot, the river guide who taught the teens everything they know, is lost to the rapids. A tragic accident, everyone agrees. Except for Nate. Mike was the best kayaker he’d ever met. The smartest. The safest. He respected and loved the river, and as far as Nate is concerned, the river loved Mike back. If his instructor was pulled under by the Starling, then Nate is sure foul play was involved. To find the truth, Nate must face his greatest fears as he retraces Mike’s final run through the Black Hole, the most treacherous waters on the Starling.
