I have a friend who has developed an academic interest in what she terms neo-Victorian kids’ lit (/MG) and YA. I have asked, and she does not draw a firm line between that and steampunk. Recommendations, anti-recommendations, interesting works to discuss: go.
I’ll start: Chris Moriarty’s The Inquisitor’s Apprentice fills my heart with joy, and I only wish she would write another, or I only wish they would publish another, or something. (That is, however, Victorian era but US setting. Not sure if it matters. Friend can show up and say so if it does.)
The Wolves of Willoughby Chase and sequels.
