Flash of Gold: A Sean O'Brien Novel

Rate this book
In the world of maritime treasure hunting, former college professor Walt Baker is about to hit the lottery. More than 300 years ago, a legendary Spanish galleon sank in a hurricane somewhere off the coast of Florida. The ship was carrying treasure worth an estimated ten billion in today’s dollars.

With billions at stake, the best criminal minds will scheme to take what’s not theirs. When they try to frame Sean O’Brien’s friend, Nick Cronus, for the murder of one of Walt Baker’s divers, O’Brien begins to put the puzzle pieces together and sees a frightening picture … not only for Nick but also for Walt, his daughter, and every member of the salvage crew.

When one of the richest treasures in nautical history is found on the ocean floor, the sharks start to circle. And as they come closer, they begin enclosing around one man, because the only thing standing in their way to recover billions is Sean O’Brien.

With Flash of Gold, Tom Lowe brings us a timeless tale of greed and murder spawned by the remains off Florida’s east coast of a Spanish treasure ship and its ancient cargo of Inca and Aztec gold and jewels. Lowe brings to his readers a zest for detail that adds to the story’s depth and excitement: whether it is the agonies of a grisly death, the laws of marine salvage, contemporary specialties like forensic podiatric analysis, or a killer pool game with a biker gang, Flash of Gold offers plenty of action and intelligence. Although the main appeal is in having PI Sean O’Brien bring a savage monster to justice, Lowe deftly balances the evil he portrays with the pleasures of O’Brien’s friendships, home, love of good food and Florida’s scenic beauty.

Tom Lowe is one of many authors I learned about through my Kindle and one of a select few I like enough to want to read.
This book, the 12th in his Sean O’Brien series, is as good as the earlier ones. With a few exceptions.
For one, the story runs just a little too long. I think Lowe could have tightened the story with no loss of depth or tension. One example is after Sean falls off the yacht. And the ‘otherworldly’ aspect of that scene was a bit of a turn-off for me. I never found those things believable.
Lowe does a good bit of head-hopping here (something I don’t remember from earlier books), something I don’t like but can tolerate if well done. And Lowe does it well except for one scene where the head hop takes place between Sean and another character who was miles away.
I noticed, too, more production errors – misplaced quotation marks, etc. - here than in prior books. And in several scenes in Sean’s POV, the ones he writes in 1st person, instead of I did something, the text read Sean did something. Someone needs to do a better job of proofreading and copyediting.
Still, as long as Lowe keeps writing stories this good, I’ll keep reading them.

My second Sean O'Brien novel this year. A great book, which once again brings up the question of why these books aren't more commercially supported. I was in a major bookstore and saw a display that included a book by the author of the worst book I've read in a long time (Overkill), but Tom Lowe's books are only available through Amazon and Goodreads doesn't even have a page count of this book (440).

A former scholar turned treasure hunter finds the wreck of a Spanish galleon, but there are those who want to steal his legitimate claim. Occasionally over the top, and sometimes too much dialog driven narrative. But fine writing, a very solid cast of recurring characters, and a well crafted plot line make this a must read.

A truly engaging and emotional story

What begins as a simple treasure hunting archeological expedition turns into a truly engaging, however brutal, and highly emotional story. When a retired ex university professor discovers, what he believes, is the wreck of a 300 year old Spanish treasure ship, then starts a trip of a lifetime. This story of adventure is criss crossed with intrigue, murder and many deaths whilst the Professor, his family and many good friends, try to salvage a 300 year old ship which had sunk with billions of dollars worth of gold, silver and jewels as well as it's cannons and armoury. A truly engrossing story which keeps you tied to your seat in anticipation of the final outcome.

Another amazing mystery!

This is another one of Tom Lowe's amazing stories backed up by reality. This one is convoluted and stretched out to include multiple different but interconnected mysteries in one book! His characters are definitely believable, with the bad guys being very scary. I love the lore of the sea and the extremely close calls that he weaves throughout this book! All of this author's Sean O'Brien books are so very good!

Sean O'Brien keeps getting better

I love this series and this author. This was a bit darker than the last one and the story line was much more developed. This had Sean really being the person who pushes the envelope, much like the earlier books in the series. I love this series and compare it favorably to the Reacher and Orphan X series. Reminds of the old Alastair Maclean books. Again, great read. A 4.8 out of 5 rating.

Sean is back!

I do enjoy the Sean O'Brien series, but it's distracting to have so many incorrect words used (dominate for dominant, conscious for conscience, sighted for cited, as examples). If not for those errors which make a reader 'trip' on the sentences and need to go back and reread, these are GREAT books!

12 Sean O'Brien Novels

I just finished the last book. They were all most excellent. The characters were all true to form and the plots exciting and varied. I felt a kinship with Sean having lived and worked in many of the story locales. Highly recommend these books and hope there will be many more.

Deadly Treasure

Sean quickly gets involved in helping his good friend Nick get out of a jam over the death of a fellow poker player whom lost a gold doubloon. This starts a whole series of killings about buried treasure and Sean getting involved in protecting friends. Great story

A Treasure Hunt with Non-stop Action

One of Tom Lowe's best, for sure. This book has it all: pirates, a sunken galleon, cursed golden treasure, beautiful women and road house drunks. And of course, Miss Maxine. Don't miss it!

Very interesting read

I really enjoyed the historical aspect of this book, I feel very enlightened. It was full of suspense, plot twist and good characters, some of the dialogue was a little lame. All in all a good read.

Sean O'Brien's friends Nick then Walt are both "persons of interest" in the murder of Walt's nephew who has been diving for Walt. Can this all be related to a possible discovery by Walt of a famous Spanish galleon that was lost in a hurricane 3 centuries before?

A real thriller...

... but please, doesn't anyone proofread anymore? The countless errors were so distracting! Ridiculous spelling and usage errors made it seem so amateurish that it was hard to take the story seriously.

Couldn't get past about halfway through book. It started out well but it just drags on. I don't need in depth description of every bar, boat, marina or for that matter everything else besides characters.

Great stories!

Thank you for 'Flash of Gold'. It was a very enjoyable read. I have enjoyed all of the Sean O'Brien stories. I can really relate with the characters in these novels. Sean, Wynona, Dave,Nick, and Max are some of my favorites. I would like to see more about Joe Billie some time. He is a very interesting character as well. Thanks again for the great stories and please keep them coming! Wade Coen

Good exciting story until the end. The bad guy surfaced too fast with little detail as to why(besides money)
