This is one of a new series by the NY Times, that makes use of their vast archive of news articles. In this case you follow the history of the Berlin Wall as seen from the pages of the newspaper written as events took place. I found it quite compelling. In a way it's like reading a book comprised of letters, sort of an "epistolary novel" except it's history.
The 'FAIL' however, is that on my Kindle Paperwhite the text is gray and barely legible. The Chapter Headings are fine, but for some reason the text itself is rubbish. On a tablet, like an iPad, or the Kindle Fire, or a Nexus it's fine. So reader beware.
I'm still giving it a 5-Star rating, because of the content, but c'mon guys this isn't rocket science. You'd think someone at the Times might do a quality check on the reader experience.
