This is the second book that I have read from this author. The first one that I read from her was Tess and the Highlander part of a Avon True Romance Teen Series (that I have to say everyone should read that series, its purely charming and witty, and definitely some of my favorite romances, great for any age!!) Anyway, let me continue on.... So The Firebrand, the title focuses on Adrienne who throughout the book is referred to a Firebrand, based on her spirited nature and temper, and boy does she have one, but it is purely charming to watch her and Wyntoun interact with one another, things surely get heated between the two, and not only just their temper (wink..wink) This story is mostly based on them, and then we get into the mystery behind Wyntoun deceiving Adrienne, although we see that it torments him all the while. This is a story with wit, suspense, romance, and the beauty of this time period that encompasses this lovely couple that learn the road of learning to trust in each others love. I just loved this book, half of the time it had me laughing, and then it had me totally entranced in this charming story.
