For the writing I would have given 4 stars, it engaged me from the very beginning and kept the reading enjoyable throughout the book, in spite of the list of other things that annoyed me.
Perhaps I would have liked the book better if I wouldn't have to what compare. I liked Sabrina well, she was a great character, however, I couldn't relate to her feelings of not being worthy of attention as I could only recently in Rose Lerner's "In for a penny". And as for Duncan... OK, it is impossible to live up to my favourite scot ever Jamie Fraser from Outlander books, but there just wasn't anything particular to like in Duncan. I guess author tried to portray him as a bit wild and "barbarian", but ended up making him hectic, inconsistent and somewhat not grown up.
The romance too lacked some logic for me. The start was nice one, but afterwards things progressed so rapidly I couldn't even follow through how they got there.
But still the book had a chance for 4 stars, because, still, it was enjoyable read. Until about around the middle. Excuse me, what kind of plot twist is that??? Something so utterly silly and stupid, and at the end just a misunderstanding and bad combination of events. And half of the story evolved around that. Argh...
