I guess this book is fine if you are looking for adventure more than romance. Don't misunderstand me, the book had romance, but I felt like the principal theme was the war, the mission to recover the treasure and the intrigue, with romance added like an afterthought.
It really got tiresome how Robert and Olivia could not trust each other or even communicate. All the conflicts between them could have been solved if they had simply talked to each other. And why was Robert always so ready to assume the worst about Olivia? Even when the evidence pointed to the contrary? It only took his brothers a moment to figure out she wasn't the killer of Orlando. And why was Olivia always trying to run away from him? She was wanted for murder, and under the circumstances Robert was the only protection she had. Where would she had gone, had she scaped from him?
And don't get me started on the improbability of two cousins looking so alike that everybody would mistake one for the other. They would have to be twins to be so alike!
In general, I really don't like to see war mixed with romance. Military men don't make my favorite heroes, nor does war and killing my favorite setting for a romance novel, and I think maybe that's why this novel is not memorable for me. The epilogue was my favorite part of the book, although I pity Olivia. Four children in four years of marriage, all this while living in a campsite while her husband did war? Poor woman!
All in all, the book was not bad, just not my favorite kind.
