As the new castellan, Sir Nicholas Beringar has the daunting task of rebuilding Ravenmoor Castle on the Scottish border and gaining the trust of the locals—one of whom wastes no time in trying to rob him. Instead of punishing the boy, Nicholas decides to make him his squire. Little does he know the thieving young lad is really…a lady.

Lady Elizabet Armstrong had donned a disguise in an attempt to free her brother from Ravenmoor’s dungeons. Although intimidated by the confident Englishman with his well-honed muscles and beguiling eyes, she cannot refuse his offer.

Nicholas senses that his new squire is not what he seems. His gentle attempts to break through the boy’s defenses leave Elizabet powerless to stem the desire that engulfs her. And when the truth is exposed, she’ll have to trust in Nicholas’s honor to help her people—and to surrender to his touch…


I received this advanced copy of “An Oath Taken” for an honest review.


Rating: five-star-rating-md 5/5


This book is a well written fantastic fantasy, keeping you on the edge of your seat the entire time with complete envy. I have always loved Diana Cosby’s books, but “An Oath Taken” blew me out of the water.

This will be the first installment in Diana’s new series “The Oath Trilogy“. Love, lust, mystery, and action fill the pages. The scenery and depictions Diana wrote were so charming and full of beauty. I was addicted after reading the first sentence. Scotland has always been a major love for me, and of course, the kilted men!

The hero and heroine of this novel were a sparkle when together. I love the twists and turns these two go through. Elizabet is on a mission, in which nothing is going to stand in her way. Nicholas is truly a wonderful, good man, but is a total alpha.

All the women in the world will fall in love with Nicholas; mysterious, sexy, alpha, the ultimate gentlemen. He ends up taking good care of Elizabet. I don’t want to give everything away so you all will enjoy reading as much as I did.

An Oath Taken” is full of love and life, action-packed with a sparkling couple. They dive right into their intimacy, and before you know it, there is no turning back.

I am already burning in anticipation for the next installment of “The Oath Trilogy.” Author Diana Cosby always knows how to take my absolute breath away. Thank you again Diana for another wonderful first installment book.

So I am ready to take another fantastic ride with book #2! Bring it on!

About the Author

author diana cosby

Most people think of retirement as a time to relax. For me, retiring at 36 from my job as a Navy Chief Meteorologist/ Oceanographer allowed me to pursue my passion—writing romance novels. With 29 moves behind me and having traveled through many more countries, I was anxious to create characters who reflected the amazing cultures and people I’ve met over the years.

I’ve written ten novels to date. Three were Viking novels set in 796, and six were about knights set in Scotland during the Bruce/Wallace era. I’ve also created a fictional precinct in Virginia Beach and have written the rough draft of my first romantic suspense. In the future, I intend to write fantasy novels—on which I’ve already begun to research.

I have many passions in life, but one that resonates in my life is that of giving. I firmly believe that each of us can make a positive difference in another person’s life. There are so many charities that I believe in. With each book I sell, I will tithe ten percent of my royalties to a charity of my choice. The first charity I’ve chosen is The National Trust for Scotland, which acts as guardian of Scotland’s magnificent heritage of architectural, scenic and historic treasures. Without the National Trust for Scotland, many of Scotland’s historical wonders would be lost.

I have an amazing family and am proud of my husband, who drag races semi-pro, and my three children who are very active within the community. The future holds many changes, including a much anticipated move to Texas where we’ll dig deep roots.
