Demonic — Karl J. Morgan

The world is on fire, and everything and everyone Bill Watson has ever loved is about to be wiped out of existence. A nuclear attack forces him to flee San Diego in the middle of the night. With his two dogs and a new friend, he heads for safety beyond the mountains. Bill is desperate to reach his family, but terrorists are everywhere and seem to be after him specifically, but why? Doors have been opened from another universe and hideous creatures have come to enslave humanity while slaughtering every Bill Watson and Mary Stewart on the planet. His family has been kidnapped, and now, Bill and Mary must step through one of those doors to rescue them and end the destruction. They will face ruthless killers and impossible odds over and again, but also learn unbelievable truths about themselves and the families they never knew they were part of. Their beliefs and faith will be tested to the limit as events spin out of control. Let us hope they are up to the challenge.
