The Secret of Haditha [EPUB ebook] 

On an unremarkable Monday evening, John Cooper and his family are thrown into turmoil when their family dinner is interrupted by a pair of unknown intruders. His son is left badly injured by the attack, and as John watches his youngest child slowly deteriorating, he is forced to face a terrifying truth: no matter how far you try to run from your past, it will always find you. With his whole world hanging by a thread, John realises that his only option is to leave his family at the time they need him most, and return to the world he left behind. As he slowly unravels the truth, John realises just how much he values the new life he has built for himself, and how far he is willing to go to protect the family he loves.
