Within the stark walls of Crowmont Hospital, every patient has a story, and every crime becomes a deeper mystery.

Psychiatric nurse Leah Smith's newest patient is Isabel Fielding, a young woman convicted as a teen for the gruesome murder of a child.

However, as Leah observes Isabel's gentle nature, she questions the girl's guilt and suspects that the real murderer might be hidden within the Fielding family. Leah isn't alone in her suspicions - renowned true crime blogger James Gorden also believes in Isabel's innocence.

As Leah grows emotionally attached to her patient, her professional stance begins to falter. She becomes obsessed with proving Isabel's innocence. But are her suspicions a product of her own dark past?

And is she prepared to put her life at risk to find out?

From the New York Times bestselling author of Silent Child, this psychological thriller series is not one to miss.
Praise for the Isabel Fielding series:
"I can't praise this book enough...it was one of the best books I've read this year!"
"Without giving too much away the characters had me fooled! Nothing is what it seems, you need to keep reading ... just one more chapter..."
"One For Sorrow is such a fabulously dark and twisted read. I knew from the opening pages it was going to be good but by heck I didn't forsee the twists and turns as they happened. It's one of those stories that you will be constantly second-guessing and jumping at conclusions only to be totally wrong."
"This dark, twisty psychological thriller was totally riveting."
