Deborah LeBlanc was born in Lafayette, Louisiana, the oldest of three children. She grew up in Scott, a small town west of Lafayette, where she developed her earliest aspiration in life; to read every book in the town library. Her first short story was written in the second grade, a tale about a misfit mermaid who grew legs. Admonished for writing the story instead of doing an assigned arithmetic lesson, Deborah's teacher confiscated the pages, and as recompense for not following instructions, gave her an additional math lesson to complete. At the end of the school day, the teacher pulled Deborah aside. Fearing that she might be forced to do additional math, Deborah listened in amazement as the teacher told her she'd read the mermaid story, thought she was a wonderful storyteller, and encouraged her to continue writing. Though the pages of that story were never returned, Deborah has been writing ever since.
