The MacGregor's Lady by Grace Burrowes

Asher MacGregor has been charged with escorting American heiress Hannah Cooper through London's ballrooms to find her a titled husband.  He has spent the last several years in Canada and the last thing he wants to do is escort someone to parties while in London.
Hannah Cooper is only in England to satisfy her step-father desire for her to marry. Unfortunately, Hannah would rather be back home waiting to be of age to get the inheritance that will protect her family in Boston.
Although neither of them want to go looking for a spouse, Hannah and Asher promise each other that they will do so on the condition that the other does the same.  In the course of "looking" for a spouse, the two develop a friendship that quickly turns into something more.
Can Asher open his heart to love again and will Hannah let Asher protect her family?
This was a great conclusion to the MacGregor Trilogy.  The whole series has me laughing out loud at the characters antics and this story was no different. 
The only reason I didn't give this a 5/5 was that Asher's history came out too slowly. Throughout the rest of the series, Asher's family talks about him and the fact that he is in Canada but you don't really learn anything about him other than he is the oldest brother. The family had to declare him dead so that the next brother in line can take over the duties of the "laird".  
I thought that Burrowes would start out with Asher's history to bring us up to speed. Unfortunately, she didn't and parts of the story were confusing to me because of this. There is a scene in which Asher thinks something and I had no idea what it meant. Later in the story, more of his history is revealed and his comments make more sense. I think that having even just a little more background information would have made the story less confusing.
