This was a beautifully profound read. It's a dark take on the coming-of-age story, exploring the violent underside of competitive sports and the physical and emotional anguish of teenage girlhood. It was fascinating to watch Ren become so consumed by her sport that it (literally) transforms who she is. As someone who did competitive swimming briefly, Ren's mindset resonated with me, and it was bittersweet to dive (no pun intended) back into that world.
