Min Jin Lee's writing style has similarities and differences to that of Kamila Shamsie (author of Home Fire).
First, both novels are broken down into books. Yet from there the structure differs: Pachinko seems to be divided loosely by location or generation, while Home Fire was separated by different characters' perspectives.
Perspective continues to be an important element in both author's writings. Shamsie chose to have one character inform just one section, yet multiple character's perspectives are voiced in each of Lee's chapters. While Lee's approach is less straightforward or easy to keep track of than Shamsie's, it does help the readers to understand how different characters think about a situation in 'real time.'
Another key element of the authors' writing styles is their use of imagery and symbols. Shamsie seems to favor long descriptions of settings and repeating motifs, while Lee's narrative appears to focus more on constant actions and thought processes. There may be symbolism present as well, but its more subtle and more difficult for me to recognize right away.
A final aspect of writing style I noticed between the two novelists was the scope of their stories. Home Fire featured only a small number of characters, a much shorter span of time, and what appears to be less geographical locations (although there were multiple). I think this strategy is good for the 'case study' approach to social commentary as it gives readers limited and specific ideas to focus on. On the other hand, Pachinko's storylines span many generations and perspectives, which I think is a better strategy for making arguments about the ways social ideals, priorities, lifestyles, and challenges shift across time and individuals.
