Hidden in the Dark

Raygan Aldaire and her friends, Max Stanwood; Claire Fisher; Jack Bancroft; Paige Kinsley; Nolan Ralston; Kayla Griffin and Andy Lakner, all have secrets that only certain people know, but they haven't told each other yet. But what kind of secrets are they? Raygan is a vampire (but a spell was cast on her so that she looked normal and she could go in the sun), Max is from another planet, Claire has some sort of super-power, Jack is the same as Claire, Paige is the daughter of a God, Nolan is a bounty hunter, Kayla is a time-traveler and Andy is a bounty hunter as well. One day, they all get a letter from someone they know as 'Master'. It tells them that they need to come together as a team and fight a man that plots to launch a nuclear attack on the world. Will they tell each other their secrets or will they end up finding out on their own?
