If you've read the very fine, "The Last Kingdom Series" and "The Arthurian Series", you'll most likely be disappointed in "The Archer's Tale". In "The Archer's Tale", Thomas, the main character, doesn't come close to the strength of Uthred or Dervel, and doesn't have enough depth to carry the story. The development of the character Will Skeat gave the reader more of a feeling for the man, while Thomas seemed to float through his life, and I found myself bored by the story. Also some of the battle scenes, especially the last one towards the end of the book, should have been better edited. Too long and far too wordy at best, but that's not to say I won't read the final two books in the series.
It's hard not to taken away with Bernard Cornwell's writing, but for me "The Archer's Tale" was weak in comparison to his other series mentioned above.
