J. A. McLachlan was born in Toronto, Canada. She is the author of a short story collection, CONNECTIONS, published by Pandora Press and two College textbooks on Professional Ethics, published by Pearson-Prentice Hall. She has been reading literary fiction, science fiction and historical fiction in equal measure all her life. Walls of Wind was her first published Science Fiction novel. She has two young adult science fiction novels, The Occasional Diamond Thief and The Salarian Desert Game, published by EDGE Publishing. And her first historical fiction, The Sorrow Stone, set in the 12th Century, is now available. She is represented by Carrie Pestritto at Prospect Agency.

Robert J. Sawyer reviewed The Walls of Wind and had this to say:
“Look out, C. J. Cherryh! Step aside, Hal Clement! There’s a new master of truly alien SF, and her name is J. A. McLachlan. THE WALLS OF WIND is doubtless THE debut novel of the year.”
— Robert J. Sawyer, Hugo Award-winning science fiction author
