Ink, iron, and glass
(Book)

A certain pen, a certain book, and a certain person can craft entirely new worlds through a branch of science called scriptology. Elsa comes from one such world that was written into creation by her mother-a noted scriptologist. But when her home is attacked and her mother kidnapped, Elsa is forced to cross into the real world and use her own scriptology gifts to find her. In an alternative Victorian Italy, Elsa finds a secret society of pazzerellones-young people with a gift for mechanics, alchemy, or scriptology-and meets Leo, a gorgeous mechanist with a smart mouth and tragic past. She recruits the help of these fellow geniuses just as an assassin arrives on their doorstep.
