Rule Master

Book 2, Rules of Engagement

This book can be downloaded and read in iBooks on your Mac or iOS device.


His rules. Her pleasure. His way.

Italian heiress and international financier Milla Castra knows she can't avoid him forever. Irredeemably confident and controlled Lex Duncan once shared her craving for things deliciously forbidden. He was her lover. Her Master. And the husband she's kept secret from everyone.

But Lex will never relinquish what's his---and Milla is definitely his. And he knows she can't resist the exquisite pleasure that awaits in his arms. When the violence of her past threatens them both, Lex will risk everything to keep Milla safe . . . before she submits to the cruelest master imaginable, Fear.

Customer Reviews

Love the Series

I knew that Sienna Snow would be one of my favorite Authors after I read her first book, and this latest installment just cemented that fact. What a hot and steamy read. I was also lucky enough to have gotten a copy from the Author in exchange for a review which I am more than happy to provide. First off I would recommend that you read the books in order, this is the second book of the series, just so you get an idea who everybody is and what our Heroine had to endure, however you could still enjoy this read if you have not. What I like most about this very well written storyline is that these are all strong independent women, they are successful and have a strong bond with each other and are not afraid to take matters into their own hands, and the men are smoking hot and have a lot going for them as well. There is plenty of steamy love scenes, if S&M is not your thing you might not agree, some action and though they were a lot of emotional ups and down the book ended on a very good note. Reading way past my bedtime has become a norm since I needed to know how it would all end. I can't wait for the next book, and I hope that there will be many more to come.

Rule Master

Milla and Lex's story is such a heart breaking roller coaster. I admit that I had to put the book down at times when I could not take anymore. I am just glad The HEA was worth it in the end.

Rule Master

After reading Rule Breaker, I was eagerly anticipating Rule Master, which did not disappoint. I was completely caught up in the steamy roller coaster ride of Lex and Milla, every bit of the trials and triumphs.

I appreciate how Sienna Snow seamlessly wove together a story with such complex, rich, strong, intelligent characters, the hardships of relationships, and the kink and sexiness that stirs many fantasies.

I'll be waiting for Carmen and Thomas!

PS...What about Ian and Caitlyn, too?
