Halloween is just around the corner and the goblins are out in force in Juniper Junction. A crotchety merchant, a malicious next-door neighbor, and some ghoulish trick-or-treaters are causing hair-raising problems for Lilly Carlsen's boyfriend, Hassan Ashraf, and things are about to get much worse.

When Hassan finds himself at the center of a police investigation following the deaths of two of his tormentors just days apart, Lilly is ready to help in any way she can to bring the real fiends to justice.

But with Lilly's daughter having trouble adjusting to college, her mother continuing a downward spiral into dementia, and possible romantic strife on the horizon between Lilly's brother and her best friend, Lilly's Halloween is beginning to look especially frightful.
