In this book, "Conqueror", author Stephen Baxter continues the "Time's Tapestry" series he began with "Emperor". Like the first book, it is a book with interesting historical detail, some strong and weak characters, all written into a series of different story arcs taking place in sequential sections of time. This makes for an interesting novel, and one that is stronger than "Emperor".
"Conqueror" begins in the same way that "Emperor did", with a new prophecy (although uttered at the end of "Emperor") that shapes the actions of the characters who try to divine and use it for their own ends. Like "Emperor", it is set in Great Britain, although this is a Britain shaped by waves of post-Roman invaders such as the Danes and Angles, as well as the full advent of Christianity. Baxter reveals his story through separate story arcs that take place in sequential periods of time (such as 793 AD, 1064 AD, and so forth), although the characters in the arcs are usually connected by either family or contact.
The historical detail in this novel is rich and, to the best of my knowledge, reasonably accurate. Baxter uses this to create some very good imagery, both mundane and terrible (one scene describes a particularly gruesome and savage act of brutality by one of his characters). Although the characters are still mixed in quality, virtually all of them are fleshed out well, and even the weakest of them is stronger than the weakest-constructed characters in "Emperor".
Like its predecessor, this novel is still largely historical fiction; rather than showing a changed past and changing future, it mostly shows the key events where changes might have occurred due to the effect of the prophecy, even if they do not end up doing so. The mysterious force called "The Weaver" remains as shrouded in mystery as he/she/it was at the beginning of the series, and the nature of the intervention in time's tapestry remains largely an attempt to shift what would otherwise be a real historical time-line.
This is probably the best novel in the "Time's Tapestry series". While I would not recommend it to anyone who has not read "Emperor", it is overall a solid book.
