known for his travels. Sam was cleaning out his Boston apartment when she discovers a picture of the Cider Brook mill among his records, along with a handwritten manuscript,The Adventures of Captain Farraday and Lady Elizabeth.
She decides to return to Knights Bridge. The last time she was there, it ended up getting her fired from her job. And Justin Sloan was one of the reasons she got fired.
This visit? He saves her from a fiery death. Sam had taken shelter in the mill during a huge thunderstorm and barely avoids being hit by lightning.
The two do a cautious, fun-to-read dance around each other. Justin's family and friends get involved, including Olivia and Duncan from the first book in this series.
A fun read. One where the majority of the story is Sam and Justin falling in love, not just falling into bed. A nice change from most of the insta-lust books that seem to be around lately.
