Weller, Mary: - Stephen and Mary Weller were born in Texas and decided it was a good place to live. Mary prefers the summer heat. Stephen prefers the winter cold. One of them compromised. Stephen is the author of two award-winning books: The Progressive Machine: Before We Called It Lean and The Progressive Hospital: A Lean Hope. Mary helped edit those books, hoping Stephen would stop writing one day. That clearly didn't happen, so Mary partnered with her husband on the next novel. This is that book.Oh, by the way, Stephen and Mary are married with kids, pets, and a mortgage. They have a passion for science fiction and anime. If you look closely, you might see them at a comic convention. Mary is the shorter one, and Stephen is the one who looks like he's lost.
