A Ghostly Affair (en Inglés) - Madeline Nixon

Talking to the dead was so not part of the plan.

Maryl Laine is certain ghosts do not exist. As a science major at Dalhousie University, she knows there's nothing that can explain them. At least, this is what she tells herself when she starts seeing the ghost that haunts her residence.

Twenty years ago, Penelope Walsh took her last breath. Her story has been told for years, whispered in campus hallways, blamed for things that go bump in the night. But the story isn't true and the only living person who knows is Maryl. As Maryl reluctantly accepts she can speak to the dead, Penny reveals she was murdered and warns Maryl away from a tryst with her teaching assistant. After all, illicit affairs can be your downfall. Solving a twenty year old cold case is the last thing Maryl expected from her first year of university. But after looping in her eccentric roommate, the mysterious guy from her creative writing lecture, and a former friend of Penny's who also has psychic gifts, detective work becomes her new major.

Maryl grapples with her newfound abilities and a whole ghostly affair in the first instalment of Maryl's Mysteries.
