Overall, I enjoyed this book and its unique approach to time travel. When I originally requested the book I didn't realize it was the second book in a series. However, I was able to understand what was going on without difficulty. Other reviews have discussed the general plot, so I will not go into that. There were some aspects about it I did not enjoy as much, such as the large amount of bloody fighting. That said, it was covering a bloody period of time, so this was likely more accurate. There was also mild cussing, which is not my favorite. Ultimately, I enjoyed the read but probably won't seek out other books in the series.

This book really caught me very early on and kept me. Very interesting concept. The characters feel so real throughout the story. Very happy with it. I intend to get the first book and wait with anticipation for other titles from this author.

“The Celtic Deception” is a solid sequel to “The Last Saxon King.” It has a good plot that keeps you on your toes; as the reader, you feel as if you are on the adventure with Dan and Sam as they are thrusted into Wales among a conflict between the Celts and Romans. I enjoyed the pace of this adventure and the characters that we were introduced to. ( )

An extremely well done time travel novel. This is the second book in a series, but there is enough background information to make it unnecessary to have read the first book. The novel is a YA book, but it is in no way juvenile; anyone, regardless of age, can enjoy it, and I, for one, did! The author obviously did his historical research, and it shows. The book (and series) concerns two teens whose fathers were members of a group of time travelers whose job was to go back in time and fix various "glitches" in the time stream; in this case, celtic Britian in the time of the Roman occupation and the Druids. There is the added complication of a rogue time traveler who is up to no good. Okay! No more spoilers! I highly recommend this book. I'll be eagerly awaiting future volumes! ( )

Celtic Deception is an entertaining tale of time travel with the unique cavet that doing so is only possible when in physical possession of a special tool which has the magical side effect of allowing the holder to understand and speak the languages around them. This is a serious difficulty with time travel. Not everyone in all times and all places speak 21st century English. But, awkwardly, one has to be physically touching the tool for it to work.
There are enough details in the story to convey a feeling for the earlier time and place, in this case Brittannia 2,000 years ago during the Roman conquest. This sense of time and place is crucial to any good time travel tale. The only unrealistic element, and one most readers would not notice, involves the condition of soil in a previously excavated spot. Original layers of soil would be disrupted and not be apparent in a subsequent excavation. I've personally done enough digging to know.
The brutality of hand-to-hand combat and the toll of dead and wounded is conveyed. The death rate from wounds, before antiseptics and antibiotics, was much higher than we realize, but the process of infection and slow dying gave people time to say their farewells. The Celtic attitude towards death was refreshing. It was seen as the next step in life's journey, not an end.
All in all, anyone interested in the mythic past, Roman Briton and the Celts would enjoy this adventure story.
