Query: a good try

i have read quite a number of time travel books and this one is perhaps the best. time travel novels usually contain many faults in the settings and characters or forced coincidences, but this book virtually doesn't leave a single detail unexplained, and the explanations certainly work well. besides lindsey has a great knowledge of history and the vivid story of William the Conqueror in the book won't disappoint you.nonetheless, i feel that the main characters seem to lack chemistry. perhaps the author should have devote more space for their romance rather than let the historical part overshadow it.still worth reading, though.
