Shaken by problems at home, confused by the motives of a new love, and reeling from a public meltdown, high school hockey star Walt McNamara joins an exclusive new leadership program controlled by the ultra-wealthy summer residents of Whaleback Island, a granite and spruce oasis off the coast of Maine. But this is no paradise; secrets lurk in its murky waters.
As Walt and his fellow misfits, including the determined Aubrey and fierce Tess, are pushed physically and mentally by ex-military instructors, exposed truths from the island's past and present slowly reveal the reasons behind their intense training. With danger mounting, Walt, Aubrey, Tess, and the others must use their new skills to sort friend from foe and find a way to survive.
