Sullivan's Promise is the last book in part of a series. Fast pace writing and reading. I thought the book was ok. I think Ryan was a jerk and it took me away from the story. This book also wrapped up the story line from other books in the series which was slightly jarring and kind of unnatural for not reading the other books. I am giving this book 3 stars because it is what you expect from the title and description. I really give it 2.5 because it was an ok book with ok characters. Thank you Netgalley and Random House Publishing for a free copy this is an honest review.
