On the whole, I think if you liked the first book, you’ll like the second. It’s more of the same, which is no complaint from me. Lee digs only slightly more into the worldbuilding of the Wastes, but as with the first book, it’s clear that’s not where Lee’s strengths or interests lie, and so she doesn’t overreach herself there, which I think is best.
The main trio—Jin, Yi-Nereen, and Kadrin—continue to be fun and engaging characters, although Jin’s self-pitying act that began at the end of book 1 grows a little tiresome, even if it is understandable. (Fortunately, she gets over it and her best traits--her courage, her determination to keep trying, her capacity to love--win resoundingly in the end.) Making a surprisingly delightful reappearance is Sou-zelle, who actually threatens to usurp our lovers as the most interesting protagonist for the first third of the book. Book 1 did a good job of making Sou-zelle a more dynamic character than merely Yi-Nereen’s jilted fiancé, and book 2 continues to give him more depth.
