Georgie, Kia, Micki, and Ace are thrown together at an elite girls’ surfing camp. At first they are not friends, as jealousy, insecurity, secrets, and lies abound. Yet they soon realize that their friendship brings out the best in each of them. But will it be too late to make the grade at the camp?

"Starfish who surf together stick together." It was Ace who wrote that in Kia, Georgie, and Micki's blue booklets on the last day of camp. Yet it's Ace who's ended up ruining everything—ending the Starfish Sisters before they've even begun. The Starfish Sisters—Ace, Kia, Georgie, and Micki—should be happy that they're on track to make the Junior Female Surfing Team. But Ace has begun to tear their friendship apart. Will lies, secrets, fighting—and love—keep them from ever being friends again?
