Morally Grey CharacterVillain ProtagonistRevenge

The Year of Self is a program many women have manifested. However, for some, the only way out is through death.

The dark reality of Dr. Carmella Carey becomes exposed as her facade of a feminist therapist comes to light. When she promotes her controversial therapy program on TV, it draws the ire of a disgruntled men’s rights advocate, Dylan Foster. When his threats go unheeded, his actions become breaking news.

She built an empire. He plans to tear it down.

A serial killer is after the women in Dr. Carey's program, and the threats are getting closer to her, but she dismisses them. Dylan harbors anger towards the women in the program and specifically wants to find his ex-girlfriend, who was an early follower of Dr. Carey’s. An assistant and a lawyer joined Dr. Carey’s team; however, neither can control their boss or her actions.

The ultimate price for power and control.


Dr. Carey has a secret life that she keeps hidden from the women of the Year of Self. As Dr. Carey's empire grows and Dylan's mission intensifies, they find themselves on a collision course, each seeking their own version of freedom, power, and revenge.

Threats are being made against a controversial women's therapy program by a bitter, twisted man determined to destroy anyone who takes part. And while the woman at the helm carries on dismissing the threats, innocent women will die. Will anyone be brave enough to go against her wishes and put a stop to the serial killer who will stop at nothing to bring her empire down?

There are some despicable characters in this book, but it was interesting to be inside their minds, and it was quite a ride! Tense, disturbing, and captivating all at the same time, The Signature Line was fast-paced, and if you love a serial killer book with some toxic attitudes that will make you think and make your blood boil at times, this one is for you!

“The Signature Line” by Nicole Annbury is an intense, edge-of-your-seat thriller that hooked me from the very first page.
Dr. Carmella Carey has built a powerful empire around The Year of Self, a controversial therapy program promising transformation for women—but beneath her polished feminist façade lies a far darker truth. As a serial killer, Dylan, begins targeting women involved in the program, the tension escalates fast.
What makes this story so compelling is the collision of power, control, obsession, and revenge. Carmella’s refusal to acknowledge the danger closing in around her only heightens the suspense, while Dylan’s rage-fueled mission adds an unsettling psychological layer. This story is full of secrets, manipulation, and morally gray characters at every turn.
Dark, gripping, and thought-provoking, The Signature Line kept me glued to the pages from start to finish. A chilling exploration of ambition and the ultimate cost of control—this one absolutely delivers.
