I'm really quite amazed at the things this novel does right. It's a detailed and grand scaled historical romance as well as being a delightful hop in magical realism, but I couldn't help make direct connections to Jonathan Strange & Mr Norrell. 
 But not because many of the ideas are the same. They aren't. What is the same is the length and the attention to historicism and the depth of the real history and especially the depth of the magic. The length of the novel and beautiful prose also has a lot to do with it, as well. 
 It's basically an immigrant story that becomes an empowerment story with a strong thread of very understated romance. The large set of characters never overwhelms the main two. The woman of Earth and the man of Fire are both magical creatures that find their way at the turn of the last century's New York City. It's really quite delightful. 
 She was created out of clay and designed with intelligence and curiosity, but she was also designed to be subservient and modest... with an evil strain built in to all golems that make them wish to utterly destroy their creators once they get a taste for blood. He was a wild spirit of fire before he was enslaved and was forced to live in stasis for a thousand years until luck would have him freed... and at loose ends in cold winters that he is unable to escape from. 
 How beautiful is that? It sounds like the setup for a grand romance. But it isn't. Not really. Theirs is a relationship based on trust and deep friendship, and even when that trust is broken, they forgive and return to each other. 
 There's even an evil wizard that returns through each life with not just a complicated background but also a complicated inner life. I can't quite call him irredeemable. He does good and and makes beauty. He made the golem, after all. But his nature leads him down very dark pathways, too. 
 So was this a character novel or a plot-driven one? Both. And wonderfully so. I got engrossed in everything. The journey was a pure delight. :) 
 I totally recommend for anyone who wants a classy and gorgeous historical romance full of deep magic and iconic archetypal characters that are beautifully drawn. :)
