Book excerpt: Can you literally sell your soul for rock 'n' roll? In the summer of 1982, the five young musicians of the rock band Entropy came close to finding out when an otherworldly entity beyond their understanding contacted them. This dangerous, terrifying being brought Entropy to the edge of fame, but ultimately tore them apart. Join Marcus F. Griffin as he reveals the true, first-hand story of his band's encounters with the Gray Man - a dark entity so powerful it could punch a hole between worlds and materialize at will. This demonic creature takes them on one of the greatest paranormal journeys anyone has ever experienced. For the members of Entropy, these real-life adventures with the Devil have never truly ended.
