I just started reading The Obelisk Gate, book two of the Broken Earth trilogy by N. K . Jemison and am lost. I've forgotten a lot of what happened in book one, The Fifth Season. Usually I go to Wikipedia but the book's article has no plot information. A Google search turns up only reviews. Where can I find a detailed plot summary of The Fifth Season?
You could try this one: http://thebooksmugglers.com/2015/08/joint-review-the-fifth-season-by-n-k-jemisin.html
I found it sufficient. Hope it helps, if it’s still necessary
