Most of the spiritual lessons from this spiritual travelogue are similar in nature to one another: you can go anywhere and find strength in God and your identity in God. Certainly a much needed lesson and worth repeating. In a book, however, it gets a little stale, unless you read slowly. That would be my suggestion, to read the book slowly, so that the encouragement Kuyper offers is somewhat fresh each time.
Also a little disappointed by the nature of the book. There are points where Kuyper shares fun travel stories, made more interesting by the fascinating information about Macchu Pichu and other places, but then she only sometimes elaborates. The spiritual lessons are often disconnected from the places visited. Rather, the lessons are more connected to Kuyper's mental and physical state at the time of travel. I believe that would make a great book: noting that we often endure trials and tribulations even while seeing or experiencing great joys. However, the stories begin with the place, not her state of life; the stories and the book itself are sold as connected to the external adventures, and as such it only partially delivers.
I'd still recommend this book for anyone struggling to find their way in life, particularly those who feel like they should feel more peaceful or joyful than they do.
