Billionaire Protector Romance Books: The Protected by a Billionaire Series

If you want steamy billionaire protector romance with real danger on the page, read Protected by a Billionaire by Anita Shaw. The series has four standalone romantic suspense novels, so you can start with any of them, and in every one a powerful man puts himself between the heroine and the danger closing in. Start with Protected by The Silver Fox Billionaire if you love an older hero and a single mom. Read FREE with Kindle Unlimited.


Some readers pick up a romance for the banter. Some come for the money. Protector romance readers wait for one moment above all, when the threat gets close and the hero steps in front of it without being asked.


What makes a billionaire protector romance work

The trope is easy to name. A billionaire, a threat, and a woman who has been handling everything alone. Add romantic suspense, and the danger isn't a misunderstanding. Somebody really is coming.


The fantasy goes deeper. It's the relief of being protected by someone dangerous, and finally feeling safe enough to stop holding it all together yourself. The money matters because it buys gates, security teams and places to hide. The heart of it is a man who decides her safety is his problem.

The small beats deliver it. A neighbor who pulls a single mom and her son behind his gates the second trouble shows up. An ex who comes back swearing he'll protect her, and won't say from what. A grumpy coach who drags her into fake dating, then makes her son laugh.

Protected by The Silver Fox Billionaire

Callie Taylor is a widowed single mom keeping her son Leo afloat on a bookkeeper's income, one late notice at a time.

Then danger lands on her doorstep, and he pulls her and her son behind his gates like it's instinct.


Expect age gap, grumpy sunshine, single mom, and forced proximity in his guest house.


Protected by My Billionaire Ex-Fiancé

Quinn Everett is a cybersecurity expert, and five years ago Brandt Corbin broke her heart. They were lovers. Then enemies. Now they're the most wanted targets in Washington. Framed for treason and locked down with the man she swore she'd never trust again, Quinn has to rely on him to stay alive.


It's second chance, enemies to lovers, and forced proximity, with a techno-thriller edge.


My Playboy Billionaire Protector

Olivia Whyte is a Las Vegas architect holding a mysterious blueprint tied to her late father, and someone wants it badly enough to break into her office. Five years ago, Jackson broke her heart and vanished. Now he's back, hotter than sin and twice as arrogant, swearing he'll protect her. He won't say from what.


This is a second chance, enemies to lovers romance with a playboy who has a lot to answer for.


Grumpy Protector Billionaire

Lily is a single mom and the team doctor for a Las Vegas pro football team. Jay Harrison is the team's grumpy coach, a former star quarterback with a chip on his shoulder. Fake dating him was never part of her playbook. One kiss for the cameras, nothing real. Then he makes her son laugh, while an anonymous blogger stirs up trouble for the team.

Frequently asked questions

What is romantic suspense?

Romantic suspense is a romance with a thriller running alongside it. The love story is the main event, but there's real danger, like a stalker, a conspiracy, or a threat nobody can name yet, and it pushes the couple together. You still get the happy ending romance readers expect.


What is a protector romance?

A protector romance is a love story where the hero keeps the heroine safe from a real threat, often as a bodyguard, a soldier, or a powerful man with the resources to shield her. The best ones make it personal, so it reads less like a job and more like a choice.
