I was really looking forward to this sequel to Holmberg's The Paper Magician, which I reviewed here. The first book served as an introduction to Holmberg's magical world in which magicians bond with specific materials through which they work their magic. However, the first story left me wanting in many areas of world building and character development. I gave Holmberg some leniency in my review because this was her debut novel and I held out hope that the sequel would fill in some of those areas of weakness.
The Glass Magician picks up shortly after the events of the first book, and we once again follow Ceony Twill through her apprenticeship with Emory Thane, The Paper Magician. Ceony's feelings for Thane have blossomed into a love that she eventually convinces herself to be one-sided. Her feelings for Thane become her mind's preoccupation, and the lovesick internal monologue grows a bit tedious. The only thing that distracts Ceony from her pining are the very imminent death threats and attempts on her life.
