This book features the Love between the millennium years old vampire Cian and Moira soon to be the queen of Geall. In this story Moira is proclaimed the rightful Queen of the kingdom by removal of the sword from the stone.Moira and Cian have been having feelings for each other since they first met in Morrigan’s Cross. She’s intrigued by him, but he has done his best to intimidate and alienate her.They know that there’s no future together, in spite of that they decide to have their happiness in whatever little time they have.
Unlike the other couples of the other two books of the circle trilogy Cian and Moira have to make sacrifices on their part, for they are not a normal couple like Hoyt-Glenna and Larkin-Blair who are joined together by not only love but also their lives. But Cian and Moira cannot as 1 is the vampire and the other the queen.
Valley of Silence also focuses on the war that has been mentioned in the first two books, final battle involving the circle and the troops they were leading facing off against Lilith and her followers.
Valley of Silence focuses on a lot of things, the love between Cian and Moira, preparation of the war,courage, sacrifices for love and humanity, humor,the jest to live even at the time of pail. What i liked most was that Nora Roberts has shown that even monsters like Lilith are capable of love. All in all this book was the best in the series. While reading this book one gets so involved that the person actually feels the emotions of the characters.
