Gethsemane fought off an attack with a sleazy hotel developer who wanted to turn her Irish cottage right into a visitor trap. But now she must encounter a vengeful ghost decided to exact revenge for a murder that occurred hundreds of years ago. This ghost’s wrath spares no one-not Gethsemane’s college students, Inspector Niall O’Reilly, fellow teacher Frankie Grennan, or the band of ghost hunters that has descended on Dunmullach to fully capture proof that spirits exist… Proof that Gethsemane has to quash to maintain Eamon, her citizen ghost and friend from getting an online sensation.

As though a spiteful specter wasn’t bad plenty of, a crooked music reviewer turns up dead in the opera-house orchestra pit, a famous composer is arrested for the crime, and Gethsemane need to team up using a notorious true-crime writer to very clear his name. Because if she doesn’t, friends will perish, a ghost she cares about won’t know peacefulness, and she’ll star in your final action gruesome enough for just about any opera.
