Time's Convert is a continuation to the All Souls Trilogy and a book in the All Souls series. It was published on September 18, 2018 in hardback, e-book, and audiobook in the US, UK, Canada, and Ireland.
On the battlefields of the American Revolution, Matthew de Clermont meets Marcus MacNeil, a young surgeon from Massachusetts, during a moment of political awakening when it seems that the world is on the brink of a brighter future. When Matthew offers him a chance at immortality and a new life, free from the restraints of his puritanical upbringing, Marcus seizes the opportunity to become a vampire. But his transformation is not an easy one and the ancient traditions and responsibilities of the de Clermont family clash with Marcus's deeply-held beliefs in liberty, equality, and brotherhood.
A passionate love story and a fascinating exploration of the power of tradition and the possibilities for change, Time's Convert will delight fans of the All Souls trilogy and all readers of magic, the supernatural, and romance.
