My co-written novella, Wrong Angle


People don't just disappear.

But there's no other explanation for what happened to Angela Cole. 

After news spreads like wildfire about the mysterious circumstances surrounding the events of that stormy winter night, Madigan Knox recognizes the face of the missing woman on TV as someone from her past. Someone she might be able to help.
Ames Soriano's persistent hunt for a serial killer leads her to South Bend, where the recent disappearance of Angela Cole parallels that of The Winter Killer's victims.
In a town where outsiders are unwelcome and with no one person eager to find the missing woman, Ames and Madigan begin a hunt for the truth and for a potential murderer with the opportunity to strike again. 

Fast-paced and suspenseful, this novella brings readers to a small town full of secrets to find a missing woman no one seems to miss. 


ALL THE DARK CORNERS, a Crimson Falls novella

Samantha Tillman had one rule after leaving Crimson Falls: Don't look back.

Not at the one thing she loved most. Not even after the murder of her father.

When her mother calls, one cold October night, begging for help, Samantha breaks her rule and returns to the town where her self-destructive coping habits were created in the hopes that she can save her.

But when she arrives at her childhood home, she is confronted with the past and people she desperately tried to forget, and the realization that a part of her never really left the town behind. 

As Founders Day approaches, disturbing events occur, and Samantha is reminded of the insidious nature of the people who reside within. Truth has consequences, and as she wrestles to find a way out of the madness, trying to escape again could cost her life.

In her latest book, O’Brien has penned a wonderfully devious story, filled with darkness and secrets that will keep you guessing until the very end.
