On "free books to read online like 50 Shades": Fifty itself isn't free, though most libraries lend the ebook through Libby. What is free is chapter one of every serial below. Of the 259 books in the NanoReads catalog, 54 are tagged billionaire and 10 are tagged contract. These seven are the ones closest to Fifty's mix. They're tagged steamy and erotic. We haven't rated every chapter, so heat here is going by the tags, and one carries an "abusive" tag, which we flag below.
His Debt, Her Body is the contract, taken further. Her father dies and leaves her five million dollars in debt to Julian Thorne, who offers to wipe it if she becomes his live-in property for a year, subject to every command. That's Fifty's contract with the safeword removed. It's tagged abusive, so go in knowing that. Read chapter one free.
Debt to the Devil gives her fifty million dollars to find and seven days to do it, and Damien Blackwood, "the Devil of Wall Street", wants something other than money. Same deal-with-terms engine, at higher stakes. Start the first chapter.
His Secret Asset flips the power. She's undercover inside Corbin Global to expose its CEO, and he looks at her as if he already knows. Pick this if you liked Fifty's cat-and-mouse emails. Open it free.
Master of the House is the power gap: her family home now belongs to Dante Bellini, and she works in it, cataloging what used to be hers, under a bargain that trades her expertise for her family's survival. Chapter one is on us.
My Controlling Boss has Zara forced to pose as her billionaire boss's fiancée at a media summit in the Bahamas, with her job on the line. It's fake dating, so lighter than the rest. Try it free.
The Billionaire's Watch is about the controlling streak. After an investigation nearly gets her killed, Rhys Blackwood locks her in his penthouse "for protection". Her word for him is jailer. Read the opening.
Reaper's Reckoning is the outlier. The hero runs a motorcycle club called the Hellhounds instead of a company, and it starts with her brother's gambling debt and a 72-hour deadline. Same debt-and-deal setup, but rougher. Begin chapter one.
