For Dash she was the only mother he had known since his died giving birth to him. So finding Lady Ashton's body destroyed something in him and he vowed someday the man who killed her would come to justice.

Lady Elena Barnes has been hiding out in Dorset behind her books. At the age of twenty-five Elena has no notion of ever finding her prince charming. Elena's debut in London was disastrous and she will forever be labeled bluestocking. Her life has become quiet and content; until her father brings her the news they have inherited a rare collection of books. Elena heads to London to catalog, pack and bring the extraordinary library to her home. Once she arrives at Lord Carrington's home Elena finds it impossible to keep her nose buried in books when Dash is around. Dash is beautiful and Elena is uncomfortable with the things he makes her feel.

THE SAINT WHO STOLE MY HEART combines mystery with passion and longing. Dash's thirst for vengeance is fierce but his longing for Elena is mystifying to him, he thought that part of him was lost to the darkness of revenge. THE SAINT WHO STOLE MY HEART has a lively plot that kept me on the edge of my seat from beginning to end. I found Dash and Elena's story captivating and delightful and couldn't help but cheer their success. I recommend this book whole heartily and encourage reading the first three books of Stefanie Sloan's Regency Rogues novels.
