I seem to have the minority opinion on this one, but I just loved this book. I think it is the writing style that appealed to me most. It is droll and understated. I much prefer this kind of dry humor over the overly-dramatic or cringe-worthy slapstick you find in so many romance novels. I also thought the plot was unusual and well done.
Liam is a simple man with simple needs, which are not being met. He endures uncomfortable travel, foul food, unruly children, and wacky Englishmen, all with good humor and letters home to his mom. He is on a quest to steal an item, which his family may or may not have a rightful claim of ownership to. His plan is to ingratiate himself with his English relatives, then sneak around in their house in the dead of night, and take the item away and hope they don't notice.
Ellie is isolated and unhappy. She is doing her best for her only child, and makes a few bad decisions. She is not a perfect person, but anyway the ethics are hazy... is it wrong to steal stolen property? Probably. But if you are going to do it, at least do it competently, and more than once if necessary, and get away with it cleanly. By outsmarting Liam, Ellie became his equal, which is a lot more satisfying than a simple story about a burly Scottsman rescuing a damsel in distress.
But in the end, it is the clear voice of the author that kept me reading. I have just added Julia London to my list of favorite authors. This book is just great.
