Books like Night in the Lonesome October

When Ed receives word from his college girlfriend that she's in love with someone else, Ed's world changes in a second. Heartbroken and half-mad, Ed goes for a nighttime walk, but on this lonesome October night, he is not alone. There are others roaming the streets, waiting to show Ed just how different his world can be. Some are enticing, some disturbing--and some are deadly, in search of prey.
