Sam Reilly #34
Caliburn's Fight :
The video was everywhere – a viral sensation sweeping across social media.
A golden retriever puppy in Bilbao, Spain. It was placed on a series of different rugs, its fur shifting in real time to match the colors and even the intricate patterns woven into the fabric. The internet was in a frenzy, with hundreds of thousands of comments debating whether it was an elaborate hoax, a genetic anomaly, or something else entirely.
But Sam Reilly knew the truth the moment he saw it.
This wasn’t a trick.
Caliburn, his dog, shared the same genetic trait.
The golden retriever was an engineered chimera infused with human and octopus DNA. He was originally designed as a classified military experiment rooted in the legendary craftsmanship of the blacksmith Merlin, who designed King Arthur’s greatest weapons – Excalibur and Caliburn.
If the puppy was real, then so too was the danger that followed it.
The hunt for Caliburn’s offspring leads Sam into the depths of a forgotten cave – where he stumbles upon an antique Basque Astrolabe that shouldn’t exist. The discovery sets off a chain reaction, dragging Sam into a deadly conflict with a Secret Society that has been protecting a hidden truth since the Lewis and Clark expedition of 1804. Meriwether Lewis was murdered to keep the secret buried.
The question remains, can Sam work out what to do with the truth, before it gets him killed too?

Sam's adventures get more daring with each book
On the internet there was a picture of Caliburn's son no doubt about it,but by the time he found the place the owner had sold Excalibur (what she named him) to a lab. So starts the search for the little pup. As true to Sam's adventures that wasnt the end oh no, the beginning. And just when you think it's all over so much more to come. Christopher Cartwright has a fantastic ability to keep you and the story on the edge of your seat. Highly recommend

Caliburn, Excalibur and Sam Reilly
Interesting how history intersects with science, and science with fantasy. Lewis and Clark, Icarus, Merlin and lots of bad guys trying to get rid of Excalibur, Sam and Tom. Loved the book with all its twists and turns. Now we wait to find out who the lady in the floating house is!

Wow!
I really loved this 34th book in the series- I can’t believe that the plot is still able to be surprising and thrilling after so many. I highly recommend this book!

Another exciting adventure
Another exciting adventure by Sam, family and friends. Always a pleasure to.read. And as usual, the Ending is a cliffhanger, leading into the next book.

Gone to the dogs
Sam and Tom fight for Caliburns son. A long trek across the continent reviels magic from the past. Entertainment at its best.

That Explains So Much!
Should have been called Caliburn’s Pup. Good story, explaining so many things! Might also have been entitled I Remember Mama!

A But Disappointed
Oh don’t get me wrong, this was another amazing novel, but he seemed do you have taken two great storylines and instead of concentrating on one or the other he matched them together and in the process didn’t really tell either story. In the end while it’s very nice read it just left you wishing for more neither storyline has a satisfaction of at least for the moment being over. I was left with the urge to throw the book across the room. And what’s worse this was a novel I was really looking forward to.

It is a very entertaining book although a bit comical about Camelot. The characters are strong and very boys own. I like the way it is written keeping interest yet suspense. Well with a read.

I liked the dog part
After they rescued the puppy and scientist, the story seemed unconnected and strange. Then it ends with a totally different story unfinished.
