This book is part of a series called Black Dagger Brotherhood. I would recommend reading this series from the start, starting with Dark Lover, as it otherwise might confuse you as this book moves on from where it left off the previous books with a few new characters.
#1 J.R. Ward’s # 1 New York Times bestselling Black Dagger Brotherhood continues as a royal bloodline is compromised by a grave threat to the throne.
Long live the King
After turning his back on the throne for centuries, Wrath, son of Wrath, finally assumed his father’s mantle–with the help of his beloved mate. But the crown sets heavily on his head. As the war with the Lessening Society rages on, and the threat from the Band of Bastards truly hits home, he is forced to make choices that put everything–and everyone–at risk. Beth Randall thought she knew what she was getting into when she mated the last pure blooded vampire on the planet: An easy ride was not it. But when she decides she wants a child, she’s unprepared for Wrath’s response–or the distance it creates between them. The question is, will true love win out… or tortured legacy take over?
