Robert Charles Wilson
Gigantic monuments to military victories twenty years in the future begin appearing around the world. This book is the story of the world’s reactions to the “chronoliths” in the decades leading up to the date recorded on the first monument. The tale is told from the point of view of a software engineer who seems to have a more-than-coincidental connection with the mysterious monuments.
The story is interesting and the portrayal of the near future is well-imagined. However, the conclusion is inconclusive, and the ending is not worthy of the rest of the story.
