ECHOES OF THE PAST
Peace was the goal. Family was the reason. But the past is never silent. In Book 2, Echoes of the Past, Bart has built a life of beauty and purpose—but ghosts return, and so do enemies. Bart must confront what he left behind… and what he’s willing to sacrifice to protect what he loves.

What Others Are Saying

The best book I’ve read since the Da Vinci Code, it has the right combination of mystery and romance to keep the pages turning until the end. The author displays an amazing touch of romance within the novel that appropriately supplements the thrilling mystery contained.
It was absolutely incredible, I struggled to set it down.
My only question is when can I have more?!
