On November 2, 1983, Sam and Dean Winchester lost their mother to a demonic supernatural force. In the wake of the tragedy, their father, John, set out to learn everything he could about the paranormal evil that lives in the dark corners and on the back roads of America ...and how to kill it. In his personal journal, he not only compiled folklore, legend, and superstition about all manner of otherworldly enemies but he also recorded his experiences - hunting the creature that killed his wife even as he raised his two sons. Part prequel, part resource guide, John Winchester's "Journal" gives fans the ultimate companion book for "Supernatural". It's all here: the exorcism Sam and Dean used in "Phantom Traveler", John's notes on everything from shape-shifters to Samuel Colt, Dean's first hunt, Sam's peewee soccer team ...and John's single-minded pursuit of a growing and deadly evil.
