The story starts with a plane that is hit by lightning and goes down. The lone survivor finds his way to the mystical land of Shangri-La. As it happens, the survivor is the future author, James Hilton of Lost Horizon. Adventurer Sam Reilly is tasked to find the ancient sanctuary to save it from an ancient struggle that will determine the existence of mankind.

The story is fast-paced and wildly imaginative. It has a real Indiana Jones feel and deals with ancient mysteries. A ton of action and suspense.

2 Stars for SHANGRI-LA by Christopher Cartwright, narrated by David Gilmore. This is a mostly Clean* novel that may be enjoyed most by YA Action-Adventure readers.

MY RATING GUIDE:
1= dnf/What was that?; 2= NOPE; NOT FOR ME/US; 3=This was okay/cute; 3.5= I enjoyed it; 4= I liked it a lot; 5= I Loved it, it was great! (I seldom give 5 Stars).

Shangri-La, 1931 ~
An aircraft carrying 2 passengers crash lands in the mountains of India with only one survivor who ultimately discovers Shangri-la.

Present day ~
Sam Reilly, his cohort Tom Bower and friends are drawn into a search for Shangri-La.

My husband and I enjoy listening to novels on audio with our morning coffee. We have enjoyed a number of Action-Adventure novels together (he’s a history buff, motor-head, science-type guy) and I prefer fast action, great adventures, creative world building with honorable and sometimes complicated characters. Our past successful “reads” have been Relic/Pendergast series, #1 by Preston & Child; Import/Matthew Riker series, #1 by J Snyder; Final Cut/Brit in FBI series, #1 by C Coulter & Ellingson; Lion in the Valley/Amelia Peabody series, #4 by E Peters; Raja’s Lost Adventure/Richard Halliburton’s Adventures, #2 by G Drake; and Uncharted/Treasure Hunter Security series, #2 by A Hackett.

I like details that pull me in (but also make sense), captivating me as I am taken across the globe and/or under the sea. Clive Cussler is one of my “go to” authors in this genre. I was expecting something along this line when I pick up SHANGRI-LA for the two of us. But SHANGRI-LA was a miss for us, as explained below. YMMV.

SHANGRI-LA ~ Cons.
1) Too much discussion (between characters) and explanations of certain concepts (telling rather than doing) which broke up the action scenes considerably.
2) The world building and various factoids required huge stretches of the imagination that logically didn’t make sense together.
3) For an Action Adventure tale, SHANGRI-LA moved too slowly for us (perhaps caused by the earlier mentioned “telling” rather than “doing”).
4) I/we were alternately bored, skeptical or confused and finished (the final half of the book) only because I/we thought perhaps everything would make sense in the end - which it didn’t. Questions raised in the beginning weren’t addressed by the end. And neither of us really cared anymore.

Pros ~
1) The narration by David Gilmore was fine. It neither improved nor reduced our enjoyment of SHANGRI-LA.
2) The concept was good. I’m always open to a new marine adventurer series. (It simply fizzled and died).
3) Readers who can suspend belief entirely and go along for the ride (as in a fantasy/“Alice in Wonderland” type world), bypass the numerous explanations and/or not particularly care if certain elements are never resolved may enjoy SHANGRI-LA.
4) SHAGRI-LA reads easily. This series may be suitable for YA Action-Adventure readers*.

We read SHANGRI-LA as a standalone title. It felt like there were pieces of information we might have missed from the earlier books, especially relating to the antagonists. Readers may prefer to begin with book #1.

*READER CAUTIONS -
VIOLENCE - PG/PG-13. Not dark.
*PROFANITY - Yes. Strong language is used on a few occasions (but probably less than most students hear on the school bus).
SEXUAL SITUATIONS - None.

Okay, I decided not to write a review of these books until I read all 21 of them. It has taken me a little more than a month to complete all of them and I can without a doubt say, I loved the characters in this series. Sam Reilly and his best friend, Tom Bower, are smart and funny men who take on the "bad guys" as they strive to save planet Earth from humanity. Their female sidekicks are equally smart, funny, but more than that they are strong and independent women. I like how Cartwright unfolds the back story of each character throughout the series, so there is always a little mystery about who they really are. I loved the stories themselves, the hunts for some of civilization's greatest mysteries and the action. Another thing I liked about the books is that the author mentions other authors and their work in some of them. As a reader it is cool to read about characters who read.

I gave three stars to 20 of the 21 books. Here is why. First, Cartwright habitually reintroduces minor characters using the same language across all of the books. It is almost as if he is plagiarizing himself. It drove me nuts. An example is his description of the Secretary of State. Second, throughout the books there are lengthy expositions about scuba diving, equipment, armaments, geography, history, etc. While some of the information is interesting, it is quite lengthy and interrupts the narrative. And when I say lengthy, I mean 5-6 pages or more. Third, there are several high level vocabulary words that Cartwright over uses throughout the books. There came a point at which I thought if the author used a certain word again, that I would scream. And I did.

I gave the final book of the series just two stars because the ending was disappointing. It just stopped and then jumped to the epilogue. While I'm unsure of whether the eluded to next adventure will be forthcoming, I don't think I will invest any time reading it.

Review:

This book delivers everything you’d expect from a great action-adventure novel—plenty of suspense, a touch of mystery, and a likeable hero who ultimately saves the day. It’s well written and briskly paced, with rapid developments and shifting situations that suit the genre perfectly.
At the heart of the story lies an ancient order concealed in shadow, a hidden battle that’s raged for millennia, and a secret meeting of unimaginable significance. The legend of Shangri-La—long dismissed as myth—suddenly becomes the focal point of a global conspiracy. When a clandestine assembly of the world’s most powerful organizations is called, Sam Reilly must unravel truth from fiction… while evading those who will stop at nothing to keep Shangri-La’s secrets buried.
The characters are engaging, and their motivations are clearly explained, making their actions feel believable within the story’s context. Overall, it’s an entertaining and enjoyable read that keeps you turning the pages.

This is book is part of the Sam Reilly series. Most books have a proper ending so they can be read as a standalone. That is also the case with this book.

Shangri-La (Sam Reilly #21), my twenty-first read from author Christopher Cartwright & the twenty-first book in the highly entertaining Sam Reilly series. A well-written rollicking thriller with captivating & well-developed main characters. The worst thing about a Sam Reilly book is waiting for the next book to be done. Reminds me of the writings of Steve Berry, Dan Brown & James Rollins. Next up is Alexander's Treasure (Sam Reilly #22) in October. (RIP Marley January 20, 2014 - July 24, 2018).

Way out there

Sam Reilly and his team find Shangri-La and prevent it from falling into the wrong hands. The problem is you have to suspend all disbelief because you are going to meet some crazy characters (Amelia Earhart?) and go through some crazy places (the 8th Continent?) and adventures (World War II shipwrecks removed in one night?) on the road to Shangri-La. The Amazon Kindle version of this book has a lot of typos, even repeated paragraphs on page 41, which distract significantly from the reading.

I was pretty disappointed with this story, I’m sorry to say. I’ve been waiting for this one for so long, and I felt let down by the pacing, locations, and ultimately the ending. The last bit of the book, which is where many many books have been leading, was too fast and didn’t make sense. I will keep reading for sure, but this did make me take a break from Sam Reilly. So many interesting elements from previous books didn’t make sense any longer, and things that have been teased were rushed and eliminated.

Review of this book.

Exceptional writing. Fast paced and full of suspense. At one point it turned into two different stories. One continued on with Sam's adventure, and the other story was about one of his crew and her brother. The author maintained excellent continuity with both stories. The end brought both stories together seamlessly. Very exciting and suspenseful. I could not read fast enough to see what happened next. I stayed up all night to finish the book. I recommend this book to everyone who enjoys this series.

not his best work (nonspecific spoiler)

I’ve loved the previous 20 books and was looking forward to this one too. It was sadly lacking on plot and, as an ER nurse, I could NOT get over Sam being up and active 1 week after major surgery which would have, IRL, taken weeks to months to recover from enough to do all the action adventuring he did! It killed the rest of the book for me.

Good read, kinda clipped.

As I continue to read the Sam Riley series, I have enjoyed most of the previous books with The exception of the Nostradamus Equation which was really not my cup of tea. This book about the mystical Shangri-La was kind of slow paced and not full of the same adventure that Christopher Cartwright has put into the others. I did read it. I did enjoy it. But just not on the same level as I expected.

This is not a re-writing of Lost Horizon. A lot of twists and turns where added to this version and it was made very exciting and I just couldn't put it down. This author was very inventive he included people who just couldn't have been there, some wonder inventions and a very unexpected ending.
I was give this book for free and only had to write a review. I really liked you should read it too.

I love all of Chris’s books and this one does not disappoint. I am a SCUBA diver, private pilot student and a Paramedic/LPN. I love the adventure elements that he adds to each of his stories that are based in fact as well as the fantasy elements mixed with real history. I can’t wait to read the next one!

What an amazing adventure and time is of the esscents. After Sam gets shot needing surgery he wasted no time to get into their next adventure. The Chinies where steeling wrecks Sam and Tom jump to the rescue, now a member of his crew has gone missing. A none stop chase to save the truth. Highly recommend fantastic adventure

Interesting

These books are more science fiction than archeological. If you like adventure stories, you will like these. Although these guys spend an awful lot of time getting almost drowned.

It started out great and exciting and then fell flat. That’s what often happens in book series that never seem to end. This one is #21. I haven’t read earlier Sam Reilly books, but I may just to compare what the earlier ones are like.

Nice easy read

If you want a nice easy read them this is well written and good fun. You don't need to start at the beginning of Sam's books of his adventures. You'll have fun reading the books.

Another extraordinary adventure

Filled with characters pulled from history, Sam and his team find the long imagined idyllic world. Only then to see it destroyed, so that a worse evil cannot sieze control of the known world through misusing it's resources

Another tale by Cartwright following the Cussler style with Sam Riley searching for Shangri-La a hidden enclave of the master builders where a power struggle is taking place. Lots of action and close calls as Sam and friends pursue their search.

Madly in love

Yes, I am madly in love with Sam Reilly. His adventures are wild and crazy and yet filled with accurate information of the history of his adventure. Dan Brown look out!

Excellent

I think this is by far my favourite Sam Reilly escapade so far as he and Tom, along with Elise and Ben separately, search for the mythical Shangri-La, encountering very strange shipwreck pirates along the way.

Mind-blowing!

I would love to know how Christopher C. plans the plots for his books! I envision a huge whiteboard with all kinds of diagrams with arrows pointing from one feature to another! Somehow all his plots work out into a wonderful story...just like SHANGRI-LA!

Lost Horizons

Another exciting adventure- this one made more interesting because Elise wasn’t there to help. Then again, Shangri-La was the destination. Page turner to the last page! Lots of fun!
