Along the same lines as the first, where they alternate between two seemingly real places (island and Berlin), here they alternate between Poland and an abandoned freighter. The plot moves slowly, as they try to decide what their next steps should be, and Briola seems to be several steps ahead along the way.
Although I really enjoyed the first book, this one seemed to drag a bit. I would have liked more answers and moving along. I felt like this was almost a rehashing of the first book, where reality seems foggy and they are given two alternatives- and we are left with our questions for a long time. This book was told from Miles's point-of-view, but because of all the action, we only get through the surface and don't get a chance to really delve into his mind.
Overall, I was really happy to get some answers about what was going on. The conclusion here was satisfying, especially after the cliffhangers of the first book.
