AJ Aalto Books in Order

AJ Aalto is a Canadian writer whose books sit at the crossroads of paranormal mystery, urban fantasy, and horror, with a streak of very dry humor running through all of it. She is best known for The Marnie Baranuik Files, a series about a forensic psychic who is sharp, capable, and not always thrilled to be around other people. That mix of monsters, mystery, and sarcasm has become Aalto's signature.

She has said she started writing at 13 after her dad handed her David Eddings' Belgariad books. She loved them so much that she started rewriting scenes and imagining all the things she wished would happen next. What began as enthusiastic tinkering slowly turned into a habit, then a craft, and finally a career.

Then she found Marnie.

For years Aalto had been wrestling with a sprawling fantasy project, and Touched began as a break from it. She has described Marnie Baranuik as a chaotic psychic detective who had been living in her head for a long time, and once that character took center stage, the series found its lane fast. The first book pulled together the pieces that still define her work: paranormal crime, ugly danger, quick banter, and a heroine who can solve hard problems while making a complete mess of her personal life.

Science matters in these books.

Aalto studied biology, and she has said that background slips into her fiction whenever she is building monsters, viruses, or the rules of the supernatural. Later, she also completed studies in criminal psychology and behaviour, which helps explain why her stories care as much about motive, damage, and aftermath as they do about blood, claws, and old world creatures. Even at their wildest, the books usually feel anchored by a practical interest in how people break, hide, and cope.

Readers usually meet her through Touched, then stick around for the way the series keeps expanding in Death Rejoices and Last Impressions. Those books deepen Marnie's world with vampire politics, ghosts, family trouble, and increasingly tangled loyalties. Blightmare and Kindred Spirits push the stakes even higher, but the appeal stays the same: a bruised, funny heroine trying to hold herself together while the supernatural world keeps kicking the door in.

Aalto also stepped outside the series with Closet Full of Bones, a darker psychological thriller about sisters, buried secrets, and the kind of pressure that can turn love into fear. Even without revenants and psychics, it still feels recognizably hers. She likes flawed people, bad choices, and the ugly ripple effects that follow both.

What readers tend to respond to is the voice. Aalto writes fast, sharp books with real momentum, but they are not just action machines. They have gross-out horror, romantic tension, oddball humor, and characters who can be loyal, petty, brave, selfish, and weirdly tender, often in the same chapter. Her work has room for the grotesque, but it also has room for grief.

She writes from Southern Ontario, and that Canadian angle shows up in the Marnie books too, especially when the series heads back across the border. Off the page, she has written about tea, gaming, and her fascination with criminal behaviour with the same irreverent tone that shows up in her fiction. It fits. AJ Aalto writes like someone who enjoys monsters, but enjoys complicated people even more.
