Mostly entertaining and a really nice trip to Scotland all for the price of an on-sale Kindle book.
A couple of annoyances: there were far too many punctuation errors (yes, where the comma goes in a sentence is important). And the sex scenes kind of cracked me up (what is it about sex scenes in books that somehow precludes the use of the word "penis"? Why do the authors always use the word "arousal" or something else?). And though the main character was in home design, I honestly did not care what she was wearing in every scene, or what her man was wearing, or other people around her. Not necessary for me.
Just odd coincidences: I've been reading the also newly released novel based on historical figures (one from Scotland and one from America) The Wide and Starry Sky, by Nancy Horan. Just so happened that I'm reading about Robert Louis Stevenson's address on Heriot Street in Edinburgh in both books. And the really weird thing is in both books characters get dogs and name them Walter. Weird indeed.
Aside from the above-mentioned items, this is a serviceable romance.
