Poor Martha Wayne. While there are plenty of comics about what Bruce Wayne's dad got up to before he was killed, from being a part of a secret society to performing surgery on a mob boss at gunpoint, there's relatively few comics written about Batman's mom.
Artist Ming Doyle, though, has imagined what a young Martha Wayne thought about her upcoming life as a wife, mother, and socialite. It's a great character portrait - and apparently the first thing Doyle did after she left school. In the link there's also interesting commentary from the artist, looking back on her earlier work.
