Debbie Lynne Costello

Debbie Lynne Costello is the author of the #1 Amazon bestseller Sword of Forgiveness, a medieval romance. She has enjoyed writing stories since she was eight years old. A true animal lover, she thought she wanted to be a veterinarian until she learned that there wouldn't always be a happy ending to each pet she treated. She raised her family and then embarked on her own career of writing the stories that had been begging to be told. 
She accepted the Lord into her life at the age of 16 and is thankful for the stories He gives her. She gives Him all the glory for everything she writes because without Him she'd not have a word to pen. She prays that the stories she tells will bless her readers and be an encouragement to them.
She loves her horses and curling up to read a good book with her Shelties and German shepherd snuggled around her. 
She and her very own hero have four children and two grandchildren and they live in upstate South Carolina. She has worked in many capacities in her church and is currently the Children's Director. When not spending time with her husband, four children or grandchildren you can find her hanging out with her Arabian horses and Tennessee Walking horses.

  4. Hi are you writing any sequels? I just finished 'Sword of Forgiveness' and loved it. I purchased an electronic copy on Amazon and it is also titles 'Winds of Change Book 1'. Does this mean there are other books in the series? Thanks! Amy
