My grandma always used to tell me: "You gotta use it or lose it deary"... How right she was.

(Book 1) "The most primal desire for humans is to survive." Life is pretty normal for our heroes as they have grown up in a pretty safe world. Stress hits them as they are about to graduate high school and finals are right around the corner. Little do our heroes know about the impending doom of the entire world as they know it. For some of them, adapting to the new world won't be that hard. For others, they will need to learn. Quickly. Trust will be tested, bonds will be formed, skills will be developed, and the fight to survive will be fought. Where will our heroes be at the end of it? Will they be standing on top of the world once the ordeal is over? Or will they be wishing they were still human?
