Lady Ironheart

Sophia-
3181 Aldsborough Way. Bring no one. We have much to discuss- and I have your key.

Lady Sophia Alderice is perfectly normal, thank you very much- or at least, she likes to consider herself so. Every morning, she must wind her mechanical heart with a key. When she awakes one morning to find her key gone and a mysterious note in its place, she has no choice but to follow the instructions- and find an underground world unlike any she's ever known. A world full of people who are like her.
