A little door that opens to a world of fairy tale wonders becomes the blood-drenched stomping ground for a gang of hunters in “Faun.” A grief-stricken librarian climbs behind the wheel of an antique Bookmobile to deliver fresh reads to the dead in “Late Returns.” In “By the Silver Water of Lake Champlain,” two young friends stumble on the corpse of a plesiosaur at the water’s edge, a discovery that forces them to confront the inescapable truth of their own mortality . . . and other horrors that lurk in the water’s shivery depths. And tension shimmers in the sweltering heat of the Nevada desert as a faceless trucker finds himself caught in a sinister dance with a tribe of motorcycle outlaws in “Throttle,” co-written with Stephen King.
