Shadow Access: A Sentinel Mutual Thriller

by Becky Mathisen, Kathy Hall (Editor)

Kayla thought she was uncovering routine fraud. Instead, she found a shadow network manipulating millions in insurance claims and burying the evidence inside shell companies.

Now she’s a liability.

As she follows the money deeper into Sentinel Mutual’s executive ranks, the conspiracy tightens. Board members close ranks. Records disappear. Threats become personal. And when the newly appointed CEO, Evan, is pulled into the crossfire, Kayla realizes the corruption doesn’t stop at financial ruin. It destroys reputations, careers, and anyone who gets too close.

With her name leveraged against Evan and powerful insiders determined to protect their empire, Kayla must decide how far she’s willing to go. Every move exposes another layer of deception. Every mistake could cost more than her job.

In a world where trust is weaponized and loyalty is currency, exposing the truth may be the most dangerous play of all.

Shadow Access is a high-stakes corporate thriller packed with financial intrigue, boardroom power plays, and a heroine willing to risk everything to bring down a corrupt system from the inside.

About the author

I write stories that explore power, trust, and what people are willing to risk for the truth, whether that unfolds inside a corporate cybersecurity thriller or a deeply personal love story. My work often draws from real-world systems and quiet human moments, where the most dangerous secrets aren’t always technical, but emotional.
