Robert Costelloe wrote fiction as a youngster, and completed his first novel a few years after college. But then the demands of family and career intervened, and his writing was mostly business or technical. But in 2005, he read an Anita Shreve love story whose ending was so abruptly despairing that he felt outrage on behalf of so many abused readers. The result was two books, Coinage of Commitment, which became a National Indie Excellence Book Award finalist, and Pocket Piece Cameo, both published by Saga Books. Again he went off into nonfiction pursuits, but in 2012, he elected to rewrite both titles for the simple reason that he could make them better stories for his readers. Both titles have been republished digitally as second edition stories, and both are available as ebooks.

Rob and his wife live near Houston, Texas.
