When Maui's biggest local surfing event of the year hits the island, Charlie plans on sticking to the sidelines, cheering for Zoe, safely away from the water. But on day one of the competition, a body washes up on shore, and it's one of Vesper's ex-boyfriends.

With Vesper quickly emerging as one of the prime suspects, Charlie, Dot and Rosie jump into action to clear the former surfer's name and find the real killer. But Jake is in charge of the case, and their new relationship is about to be dealt a challenge as they decide to take different tracks.

Add to this the problem of the gangsters in Seattle, and Charlie has her hands full. Will she save her relationship with Jake and solve the case, saving Vesper's freedom in the process? Or will the killer get to her first, causing Charlie to wipe out—permanently?
