Great White Sharks were once hunted to near extinction. But now they're back. And in the resort town of Surf Shore, people are dying.Carson Sheridan has dedicated her life to shark conservation, but can't deny the horrific series of attacks that point unerringly to a massive Great White - all off the same beach - all at the same time of year. Great Whites in California are in historically large numbers and record sizes. But the waters off Surf Shore are particularly deadly and Carson is about to discover why.Is it a single killer? A big aggressive shark, returning every season? Or, even worse, is it an exploding population - an ocean full of twenty-foot monsters?And why here at Surf Shore? Again and Again? Carson is determined to find the reason... and the answer just might cost her life.
