I was disappointed in this book. I wish it woupd have gone into more detail about Mars. Lile their homes, food and general way of life. It shad very little descriptions for some things but then whole paragraphs for things like a desk or a bookcase. There were characters who appeared and disappeared with very little dialogue or description such as mira and runge. I half the time had no clue what was even happening. I dont really understand the point of the book. I thought the relationship between earth and mars was very confusing. I dont understand the reason for the tower of Babel. The whole central archive thing was hard to understand. I spent the entire first half of the book completely confused and lost.
