Supernatural: Rising Son — Rebecca Dessertine

Dean and Sam Winchester were raised as Hunters by their widowed father, seeking vengeance on the supernatural elements that took their mother from them. But the road to vengeance is a dark one, and is it a place where children can have any semblance of a life?

Picking up several years after Supernatural: Origins, the boys are now old enough to join John on his cross-country "hunting trips." Amid the carnage and violence, John's seeking something specific: any information on why his wife was murdered. But is he prepared for the answers that he'll find? And is he willing to sacrifice his 11-year-old son Dean to this hard, lonely life by giving him his first "hunt"?
