I absolutely love this series!! Kamery Solomon is a fantastic author and her attention to detail (historical and visual) is outstanding. I fully feel like I am in the book experiencing everything with the characters.
There are three different perspectives that split the book into three sections. We start off in modern day with Scott Williams who soon discovers that his friends did not die, but in fact traveled through time. He learns a little too much, however, that ends up endangering himself a bit from those who would do the Knights Templar harm.
Then we see Mark Bell's perspective in the past as he struggles to see someone he loves, Sam, and her husband Tristan back together again after being with Sam so long in the second book. But not all is what it seems, and soon he realizes Sam has been struggling immensely since their return (no spoilers, but it is very sad) and he tried to help her husband Tristan pick up the broken pieces of her heart. As much as seeing Sam in love with another has hurt him, I think he'll be okay. There is another love interest on the horizon. If he could just get out of his head and accept it that is.
Sam's perspective is always my favorite because I love all of the Tristan and Sam moments. They really are a perfect couple! Sam is such a strong heroine. Even after all she's been through, she keeps fighting. She did have a bit of a struggle, but once she was back on the sea with her husband (even though the circumstances were not the best) she became herself again. I must admit, I cried when those that were lost came to visit Sam and Tristan (that was probably one of my favorite scenes of the book) and I cannot wait to continue the series in book 4.
