Quick very high level summary.
The Nameless Land continues the Journey begun in The Witch Roads. The royal party finds themselves in a mythical land they never imagined they would reach. Its a journey of betrayal, difficult choices, with consequences of the past and demanding that the characters constantly fight for survival. While Erin confronts her past, Prince Gevulin must forge alliances If they wish to survive this journey.

My Take.
The world building is amazing. Such a vivid picture of the politics and social class that are at the center of the plot. There is a lot of information to take in so those who are not used to epic fantasy world building may find it tedious and a bit overwhelming. Me personally, this is just the kind of detail I live for. Elliott paints not just a picture of the journey but she pulls the reader in and immerses them in the story. Through out this book we see both the Prince and Erin continue to develop and grow as they face many life threatening challenges. Overall I enjoyed this book just as much as the first. We are left with some open ended questions so I am sad this is a duology but not mad about the ending at all.

And now we get to see Elliott swing for the fences in the best kind of way, playing around in the spirit world she's developed and also further developing and wrapping the politics thread of this duology. It also gets to wrestle with that unique feeling you have of someone you care for getting ready to strike out on their own, and that blend of fear and pride you have as you watch them take their first steps out into the world, and also reemphasizes that one is allowed to have a life beyond someone who's long gone. Bittersweet, but a perfect ending for this duology.
