Inner Demons

Book One out of a Trilogy:
Four young boys are adopted by a mysterious woman, Mrs. Warwyke. Throughout their childhoods they had hardships that they had to overcome, eventually escalating to the point of where they lose their parents. Nobody really understands why yet, but they feel that Mrs. Warwyke has some things that she is hiding from them. They were born with powers that are not under their control yet. But they have to get going, the end of the world is near, and most of humanity will soon be wiped out of existence unless they can somehow stop the dark force and his evil minions from doing so. So now, we can end this with a question: We were all placed here for a reason, correct?
