Book excerpt: Would you travel to the past to right a wrong? Solve a cold case? Perhaps, catch a killer? Meet one of the five witches who will. Animal mauling or were attack? Time witch Nuala Walsh is on the case. Ex-communicated from her coven at a young age, Nuala uses her powerful magic to solve cold-cases for the Agency of Paranormal Peculiarities. Only the cases become less cold and fresher as each assignment sends her back in time to work out the clues the mortal investigators can’t dig up on their own. Each assignment comes with a strict set of rules and a time limit and Nuala enjoys leaving her present drama behind to bust criminals in the past. But Nuala has one rule of her own—no kids. When she receives a case from 1985 involving an all-girls reform school, her only instinct is to say no. Teenage girls are the worst kind of drain on her magic. But the file reveals a familiar name she hasn’t heard in years and suddenly the murder of the school’s headmistress becomes less off limits and more of a personal quest. Can Nuala keep her 100% case closure rate without losing her head -- literally?
