Neptune's Fortune: The Billion-Dollar Shipwreck and the Ghosts of the Spanish Empire

by Julian Sancton

The riveting true story of a legendary Spanish galleon that sunk off the coast of Colombia with over $1 billion in gold and silver—and one man’s obsessive quest to find it—from the New York Times bestselling author of Madhouse at the End of the Earth

Roger Dooley wasn’t looking for the San Jose. But an accidental discovery in the dusty stacks of a Spanish archive in the 1980s led him to the story of a lifetime—the journey of a ship that had gathered a mountain of riches from the New World for a long-awaited delivery to the King of Spain nearly three centuries earlier. But that ship, the galleon San Jose, never reached its destination. Instead, the Spanish treasure fleet was drawn into a pitched battle with British ships of war off the coast of Cartagena. When the smoke cleared, the San Jose had disappeared into the ocean.

Though a diver at heart, Dooley was an unlikely candidate to find the San Jose. Half Cuban by birth, he lived a life that stretched from the ballfields of Brooklyn to the shores of Castro’s Havana at the dawn of revolution, where he would help birth a fledgling nation’s diving program and make films with the likes of Jacques Cousteau before finding himself placed on an international watch list and barred from the United States. Dooley had little in the way of serious credentials, yet his tenacity and single-minded devotion to finding the San Jose—led him to breakthroughs once thought impossible. As he jousted with famous treasure hunters and well-funded competitors, Dooley ultimately homed in on a patch of sea that might contain a three-hundred-year-old shipwreck—or nothing at all.

Neptune's Fortune plunges into a rarified world through the eyes of an idiosyncratic protagonist, one whose work would spark the hopes of presidents and make real the dreams of a nation. This tale of temerity and treasure is a one-of-a-kind story of a lost fortune and the decades-long quest to shine a light on the bounty at the bottom of the sea.

I had high hopes for Julian Sancton's newest, Neptune's Fortune. After all, Madhouse at the End of the Earth is a perfect mixture of claustrophobic horror and perseverance in the age of polar exploration. It was a tight narrative, which left me, a shipwreck addict, supremely satisfied. Of course, seeing that Sancton was taking on a different shipwreck meant I knew what I was going to get all over again. I was psyched.

Instead, Sancton went the complete opposite way. Neptune's Fortune is a story that crosses hundreds of years, tackles international politics, and follows a man who may not be able to be trusted. This isn't Madhouse Part 2. This is completely different and still utterly fantastic. I demand that Sancton never write about anything but shipwrecks. (Please.)

This book is three parts. The first tells the story of how a Spanish galleon, the San José, ends up on the seafloor with over a billion dollars in gold and silver. While this is only the first part of the book, Sancton is not rushing. The battle was so engaging I literally stayed up too late to make sure I finished that part. The second part follows Roger Dooley. Who is Roger Dooley? Probably easier to say what he isn't. Let's just say he is a treasure hunter. For good or bad, well, like everything else about him, it's complicated. The third part follows Dooley as he goes searching for the San Jose.

Literally nothing about this story is simple. Did the San José blow up? Is Dooley a liar or an obsessive genius? Even if the San José is found, who actually owns it? There are so many ways to take this narrative and Sancton always makes the right choice. It's a must-read.

While not as riveting as Julian Sancton’s inaugural effort, the highly enjoyable “Madhouse At The End of The World”, this is nonetheless an engaging story on one man’s quest, Cuban-American Roger Dooley, to locate what can be considered the mother lode in the era of galleons of the Spanish treasure fleets of the 16th-17th century period, the vessel San Jose.

The book is divided into three parts: the story of how San Jose came to fall victim to an English fleet of marauders seeking to hijack the enormous stash of gold and silver aboard. Part 2, which bogs things down a bit is a profile of the 5 most illustrious shipwreck hunters/marine salvage specialists, focusing on the discovery of the infamous Atocha in 1968, as well as Nuestra Señora de la Concepcion and others.

Part 3 focuses on Dooley’s obsessive hunt to locate the San Jose, which, aided by then new technology courtesy of Woods Hole Oceanographic Institute as well as archival documents and maps, he manages to locate. The story ends on a bit of a bittersweet note, as the reader is apprised of all the geopolitical pitfalls that come with discovering a shipwreck. Who benefits? The nation of origin…the country which served as the port of departure…the nation whose territorial waters the vessel resides in? What about the nation(s) that had its inhabitants exploited to mine for the gold and silver contained therein? It’s all a classic study of being careful what you wish for and how politics and money become embroiled when all one wanted (in the case of Dooley) is to preserve and honor the past.

A mostly self taught diver and ocean archeologist yearns of finding the big treasure. From his childhood in Cuba to moving to the U.S. Roger Dooley was determined to find the largest Spanish sunken treasure shipwreck in history. The problem is he had to locate it without knowing the general area where it sank, searching for any documents over 300 years ago, then finance it and then put a claim on it before local governments or other treasure seekers could. In superb storytelling Julian Sancton shares Roger Dooley's life and obsession with finding the San Jose as well as the history of Europe's thirst for gold and silver that led to the fateful battle and ship sinking and the early history of deep sea wreck exploration and treasure salvage. The one and a million chance he would find it and the toll it would take. Armchair history buffs, wannabe treasure seekers and curious readers who enjoy a biography of a man who wouldn't give up on his dream. It is an enjoyable and thrilling journey that readers of the Key West Florida treasure hunters, the search for the Titanic and THE WIDE WIDE SEA will enjoy. My thanks to the publisher for the advance copy.

Thanks to NetGalley for the e-ARC -- this is a tricky one to rate because the first part of the book, featuring the history of the Spanish Armada's routes through the Caribbean as well as the engagement with an English squadron that ultimately sank the San Jose was excellent. Couldn't put it down, great history, and I learned a bunch about Spanish galleons of the period. Once the second part of the book got going, this was firmly a biography of Roger Dooley's life, with the occasional chapter veering into other revelant information, and while some chunks, such as Dooley's adolescent years alongside the early years of Castro's regime in Cuba, were very interesting for how little I knew about the period and region, the in-depth writing on his whole life definitely dragged in places, and unfortunately the lead-up to the discovery of the San Jose wreckage was one of those places. It was a good book, it just didn't seem to hold the momentum throughout. Very much worth reading if you're interested in shipwrecks and undersea archeology!

This was such an engaging read. Started it in the waiting room at my GP and did not even mind NOR notice the wait time because I was INHALING this book. It's rare that someone gives me the feeling they're obsessed with the subject they're writing about but also self aware enough of that obsession to turn it to the advantage of the research and the story and this book strikes the balance for me.

[Mara · Rating 5 out of 5]

I knew nothing about the Spanish galleon San José (or its wreck) before I picked up this book, but Julian Sancton's writing has me hooked from start to finish. Got goosebumps several times, maybe almost shed a tear. I will protect Roger Dooley with my life, why does this man not have a Wikipedia page!
I'm already looking forward to whatever Sancton will dive into next.

"The sea is broad and her paths are many."

I read Sancton's other book, Madhouse at the End of the Earth: The Belgica's Journey into the Dark Antarctic Night, as part of my deep dive into arctic exploration, and was really pleased with the result. I somehow missed(!) that he has another book coming next month (and will absolutely pick it up soon), but did manage to snag the ARC for this upcoming book of his. I went into it basically blind; I didn't know much about either the San Jose or treasure hunting in general, but I ended up walking away with more treasure hunter knowledge, historical and naval knowledge, and information about the players involved than I expected.

This book covers a lot of ground in its journey to the San Jose. The opening few chapters recounting how and why it sunk in the first place set the stage for later on, but also were interesting in their own right. I thought the different accounts for the lead up to and the actual battle of was a nice touch; you get to experience multiple angles of the incident. After this introduction of sorts, we're thrust into the role of Dooley-watcher, where we're introduced to him first later in life and then from childhood on up in Cuba. I sort of thought the Dooley life chapters were a mixed bag; some were really interesting, and sort of shows how and why Dooley made the choices he made later on, and some felt a bit extraneous and made things feel a bit slow. The treasure hunter asides were universally interesting to me, as was the actual search for the San Jose later on. Lots of neat footnotes are included here, particularly about the preponderance of shells around the wreck site and the connection between them and bones. Nature is metal.

I will say that I sort of expected a bit more about the wreck itself. It felt like by the time it was located, the book was basically over. With what happens later, I guess that's to be expected, but it felt a bit anticlimactic given the title of the book. But as a book about treasure hunting vs. deep sea archaeology, I was very pleased.

Thanks to the publisher and NetGalley for a free e-copy of this book in exchange for an honest review.

[Brandon Gryder · Rating 3 out of 5]

An exhaustive (and exhausting) tale of the shipwreck of the Spanish galleon San Jose. Unfortunately the book focuses on the legal minutiae of treasure hunting instead of the actual discovery of an important shipwreck. In hindsight I probably should have expected this.

[Natalie Giglio · Rating 4 out of 5]

4.65/5 - I’m really not sure how I came about this book but it was an entertaining and educational read. Written by a journalist, you follows the life’s journey of Roger Dooley who is a Cuban “maritime archaeologist” whose life mission is to discover and excavate the famous Spanish galleon, the San Jose. The story shows the purest form of determination and passion. The writer spent 5 years interviewing and piecing together this story. What was craziest to me was that a ship that sank off of the Colombian coast in 1708 was being investigated, studied and searched for in the 2010s. I had no idea that governments and researches were working on this project.

Quite enjoyable, a blend of history of the Spanish empire with modern day treasure hunting, all with a keen eye for human interest.

[Karyl · Rating 4 out of 5]

A while back, I read the author’s Madhouse at the End of the Earth: The Belgica's Journey into the Dark Antarctic Night as part of my sad boat obsession, and absolutely loved it. I had gone into my local indie bookstore, and the owner gave me this ARC to read, knowing how much I enjoyed Sancton’s earlier book. I admit it took me entirely too long to read it, but it was quite the ride!!

The book opens with a discussion of the Spanish empire and from where came the precious metals that European colonizers were obsessed with. It’s insane to think of how much literal treasure was on these ships that were bound back to Europe; everyone on the ships would have huge quantities of contraband that was hidden from the Spanish authorities, so it’s difficult to know exactly how much riches were on each journey. But suffice it to say it was A LOT. Hence why there have been so many treasure hunters wanting to find these shipwrecks as a quick way to become insanely wealthy.

We also see the battle that sunk the San Jose from multiple angles. This gives a really clear picture of what exactly had happened, though for hundreds of years it was unclear exactly where.

Enter Roger Dooley, an American raised in Cuba during the Castro years who found refuge under the sparkly waters of the Caribbean. Though initially he comes across as a little suspect, Sancton shows that Dooley was motivated mostly by the hopes of learning new information from these wrecks. For him, the treasure was secondary. He wasn’t in it to make money, unlike many of the other treasure hunters Sancton profiles. It hurts my heart so much to think of the damage these men did to these historical sites by blowing up the coral and the wrecks in hopes of getting their hands on gold and silver. Knowledge meant nothing to them.

It was also interesting to see how Colombia handled the discovery of the San Juan site, and how it changed depending on who was president. Having one president act out of spite regarding his predecessor is somewhat amusing, though sad at the same time.

I really hope people enjoy this book. I wish I had been able to give it more of my attention, but I am so glad to have read it. Sancton is quickly becoming a must-read author for me.

Interesting story full of adventure and intrigue. Disappointing ending,not on part of the author but just the malaise of events and frustration experienced by the reader at the lack of a satisfactory outcome.

This was a fun book, thank you to Netgalley for the ARC in exchange for an honest review.

As a history buff but not all that familiar with this particular wreck, I found the historical piece interesting and enjoyed reading about the process to find the galleon.

I liked the authors style here, it was very readable and made you want to root for Dooley. Pacing overall was pretty good, and while there was a lot of background on Dooley, it felt about right to paint the picture of who he is and what helped drive him to his fascination.

Book #4 of 2026
By now you probably know I love books about ships, shipwrecks, high seas exploration, buried treasures, etc. and this author’s debut novel, ‘Madhouse at the End of the Earth: The Belgica’s Journey into the Dark Antarctic Night’, is among my favorites!
Julian Sancton’s sophomore effort, while not quite as bone-chilling as his first (see what I did there…), is a superbly researched and fascinating book about one man’s obsession with finding and excavating the legendary Spanish galleon known as the San Jose. The ship sunk off the coast of Colombia over 300 years ago when it was attacked by an English warship whose captain and crew sought to steal approximately $1 Billion worth of gold and silver believed to be aboard the San Jose and en route to the Spanish king.
I thoroughly enjoyed the book and learned quite a bit about European colonialism along the way.

[Aoibhe MacManus · Rating 5 out of 5]

This mans passion, determination, and resilience is honestly inspiring. An interesting story that highlights the power of optimism. Also a great history lesson on the Spanish colonisation of the Americas and an insight into the world of maritime archaeology.

[Erica · Rating 2 out of 5]

I did not care for the way this was written. I thought it would be similar to The Wager, but it is very history heavy with backstory before even getting to the shipwreck and the Spanish Empire. It was a bit of a slog to get through.

[Jessica · Rating 3 out of 5]

There was an audible gasp out of me, when I saw this book was coming out. I so dearly loved the first book by this author, and eagerly started this newest story, expecting to get wrapped up in the history, the writing, the journey.

And I did. At first. The history of treasure galleons, of the cities that popped up along the shipping lanes and the people that ruled them, of the sheer amount of money, goods, treasure that floated around the globe, that was lost at the bottom of the ocean…it captivated me.

And then the story shifted. I didn’t hate that the author moved to the history of Roger Dooley - didn’t even really mind when he took us through the history of Cuba, Castro, and diving in Cuba. It was fascinating, and still managed to keep my interest for a while longer, but it was when the story moved into covering The Big Five that my interest waned.

Just…the avarice. The machismo. The disregard of the men who literally blew up history to satisfy their need.


And it’s nothing against the author or the history he shared. But this one just didn’t move me - didn’t draw me in - as easily or quickly as Madhouse. And maybe I was expecting too much, but how could I not?


It was like reliving my playthrougsh of Sid Meier’s Pirates! reading through the first few chapters. It was an adventure, just what I was looking for from the book. And then…it wasn’t.

[Catherine Rodriguez · Rating 4 out of 5]

The discovery of the wreck of the San Jose happened recently (2015), but it was nowhere on my radar until I heard about this book. What I think is so fun about this read is that it's so rooted in history and, at the same time, concerns a present-day matter. It was only this past November that they started excavating historical artifacts from the site, which I had to google because, at the close of this book, no concrete decisions had been made as far as excavation, preservation, etc. I find this interesting because, usually, I'm reading about history that happened a hundred years ago and is over and done with (as much as one can ever be finished with history and its ripple effects). But this is fresh! This is happening now!

Of course, the disaster that sent the San Jose down happened a couple hundred years ago, which the author provides background on. They also shed light on the tradition of treasure hunting and the big names in the field who, for better or for worse (usually for worse), made it seem daring and adventurous and lucrative. The primary person we tag along with is a guy named Roger Dooley, as he's the one who spent decades tracking down archival materials, getting experience and education in deep sea archeology, and is the mastermind behind locating the wreck. Part of this story is understanding his biography and his purpose for never giving up on finding the San Jose.

From a craft point of view, this was well-written and pieced together nicely. There are a few different sections because we get context and background on a few elements that paint a bigger picture of the world Dooley was operating in, but it never felt like we were being thrown around to one topic than the next. It was thoughtfully layered together.

I'd recommend this book to anyone interested in shipwrecks or stories that are National Treasure-esque. Or for anyone who's like me and never had dreams to dive into the ocean and see what can be found in there. To me, if it's lost to the ocean, that's the ocean's business. Yet, I love picking up books like this one because, in a way, I can experience this niche thing that I'm not going to get myself into nor care to devote my life to. I can read about something that's so different from my hobbies or what I see on a day-to-day basis. This is the kind of reading experience that delights me that books like this exist.

[Mike Lawton · Rating 4 out of 5]

Neptune's Fortune is three books compressed into one, and how much you enjoy it depends on which book you're reading at any given moment.

The strongest section by far is the opening — the history of the Spanish and English navies of the era, the treasure fleet system, and the 1708 battle that sent the San José to the bottom off Cartagena. Sancton brings real energy to this, and as someone who seeks out naval history, I was in my element — but also left wanting more of it. It's the kind of history that makes you want to pull on a thread and keep pulling, and the book moves on from it too quickly.

Roger Dooley's biography is the heart of the book, and mostly it earns that place. His childhood in Cuba, his early diving career, his complicated entanglement with Castro's government, his work alongside Cousteau — it's a genuinely fascinating life, and Sancton renders it well. Dooley is an Ahab figure, the San José his white whale, and that obsession gives the book its spine. Where it gets murkier is in the portrait of Dooley's ethics. The book tries to position him as someone more interested in archaeology than treasure, and I mostly bought it — until his reactions after the discovery undercut that reading somewhat. He's a man trapped in the world of treasure hunting who may or may not have fully made peace with that.

The middle section profiling the "Big Five" treasure hunters provides useful context, but it's the section where the book loses momentum. These men exist as background — to show the cutthroat, legally murky, historically destructive world Dooley was navigating — but Sancton spends more time with them than the story needs.

The geopolitical tug-of-war over who owns the San José is surprisingly compelling, particularly Colombia's shifting positions depending on who held the presidency. It reads as a clear illustration of how politics can weaponize history.

The ending is genuinely anticlimactic — the wreck is located and then the book is essentially over. There's not a clean alternative given the real-world circumstances, but it still lands with less impact than the journey deserved. And for a book called Neptune's Fortune, you'd hope for a little more time with the ship itself once it's finally found.

Still, this is rich, well-researched narrative history with a compelling central figure and some genuinely thrilling passages.

[Brenda · Rating 5 out of 5]

Neptune's Fortune by Julian Sancton is the real-life adventure of the 18th century Spanish galleon San José crew, the blood-pumping battle with the British, the ship's disappearance off the Colombian coast, and the obsession of a man three hundred years later who was eager to find something no one else had.

American Cuban Roger Dooley's passion for archaeology and diving took him on treasure hunts amidst danger and political tensions. President Fidel Castro had ordered him to pry riches from Cuban shipwrecks. After finding and reading a packet of letters about the San José gold and silver and deaths of those aboard, Dooley knew he had to search for the biggest treasure in the history of humanity, worth more than a billion dollars. His goal was more than the monetary value...the artifacts themselves. But hurdles abounded, including a custody battle between several countries and groups.

The author's experiences with Dooley are amusing and fascinating. I appreciate the explanation of Dooley's childhood (especially his brother), craving for adventures. pursuit of ambitions, history such as the significance of Jacques-Yves Cousteau, and geopolitics. This book is loaded to the gills with nuggets of information. The footnotes are helpful.

Descriptions of jewelry and fingers of gold and silver in the market as well as the all-sensory atmosphere of the foods, livestock, and pests aboard the San José crackled with atmosphere. I could taste the salt cod, hear the livestock, feel the creepy crawlies, and smell the wormy mush. Battles and mutiny abounded.

From beginning to end, this book has everything an adventure lover could wish for! Brilliant research and storytelling to boot.

This book, the second book by the author of my favorite nonfiction (Madhouse at the End of the Earth), did not disappoint! 

The San Jose, a Spanish galleon, was sunk during battle with English ships in 1708, off the coast of Cartagena, Colombia.  Carrying a vast treasure of gold, silver, gems, and more, the ship is of unprecedented historical value as the most perfectly preserved Spanish Galleon ever discovered. 

This book is centered on the Cuban-American  Archaeologist, Roger Dooley, whose life obsession with the San Jose, led him to its discovery in 2015, after thirty years of meticulous research.  Since its discovery, it has been in the middle of ongoing international politics and litigation. 

The majority of the book is about Roger Dooley's search.  He was exhaustive in his research from the years he spent at the General Archive of the Indies in Seville, Spain, to a map he found at the Library of Congress, research in the U.K., and the time he spent talking to people along Colombian coastal towns, finding clues in the lore and stories about the San Jose that had been handed down through generations.  He managed to meet with Presidents of Colombia and other high ranking political persons, both through his Colombian wife's connections and also by crashing events and parties -- and people were soon caught up in his unceasing enthusiasm and boyish excitement.

As a bonus, there are many interesting sidebars that had me stopping and looking online for more information, such as:  where did gold and silver come from?  A recent theory is that it starts with the collision of two neutron stars....

The story of a Spanish treasure ship that sank off the coast of Columbia in the early part of the 18th-century. The San Jose was thought to contain over one billion in gold and silver and has rebuffed various efforts to be discovered. The obsessive quest of Cuban-American archaeologist Roger Dooley is highlighted.

The followup to the author's excellent debut, 2021's "Madhouse at the End of the Earth" is another nautical themed adventure. This time, Sancton takes the reader to the warmer waters of the Caribbean Sea as we follow the tireless quest of Dooley to find the remains of a Spanish treasure ship that sank in 1708. I was heavily invested in Dooley's story. His peripatetic life story was fascinating as was his quixotic quest to find the infamous ship, the San Jose. It was also rewarding to read of Cuba and its time under the repressive Fidel Castro regime.

I will admit to losing a small amount of enthusiasm for the story after the ship is finally discovered in 2015. As Sancton makes clear, that event was not the end of this story, but rather a new beginning. The political wrangling that involves the governments of multiple nations, court systems and various salvage companies grew a bit tiresome. A small complaint, but one that precludes this book from reaching the heights of "Madhouse". Sancton is an excellent investigative writer and I look forward to what he has in store in the future.

[Madeleine · Rating 2 out of 5]

Julian Sancton's first "boat book" was about the Antarctic, so definitely more my sweet spot than this one - but he is a good writer/journalist, good at arranging events into a narrative in a compelling way and making the dry somewhat exciting.

Unfortunately the topic of this book compelled me much less. It started off well, with the backstory that led to the Spanish galleon's sinking, and finished with the long-awaited discovery of the wreck, but ultimately took a long detour through the life and character of Roger Dooley, which, while interesting, and still often maritime archaeology-adjacent, also felt like a lot of filler, taking us through Castro's Cuba and Colombia and modern treasure-hunting and every decade of Dooley's life. Sancton is passionate about it, but it didn't surprise me to hear it had started out as the topic of an article. (And in my honest opinion, it probably could have stayed that way.) I think the other issue is that, for all Sancton's thorough research, it pales besides other works about maritime archaeology that I've read (e.g. Mensun Bound's book on the Endurance) if only because they have the benefit of a first-person narrative, the expert in their own voice, to give things a little more immediacy. So I liked the start, and it picked up again when we actually got to the San José, but the middle wasn't as thrilling.

[Stephen Lyons · Rating 5 out of 5]

This book was amazing on multiple levels. Once I picked it up, I couldn’t put it down—I was completely immersed, feeling as if I were alongside Roger Dooley himself, chasing something just out of reach beneath the ocean’s surface.

This is my third maritime read of the year, following Zorg and Endurance, and it only deepened my appetite for these kinds of true stories. There’s something uniquely compelling about the combination of history, risk, obsession, and the unknown—and Neptune’s Fortune delivers on all of it.

At its core, it’s the story of a ship that sank in 1708, but what makes it so captivating is the centuries-long mystery and pursuit surrounding what lies beneath. Sancton does a great job weaving together past and present—blending historical narrative with modern-day exploration, ambition, and the relentless human drive to discover and recover.

What stood out most to me was the tension between possibility and reality—the idea that unimaginable treasure may sit just out of reach, and the lengths people will go to chase it. It’s not just about gold and artifacts; it’s about obsession, endurance, and the pull of unfinished stories.

If you’re drawn to adventure, history, or the psychology of pursuit, this one absolutely delivers. A gripping, fast-moving, and thought-provoking read that lingers even after the final page.

[Paul · Rating 4 out of 5]

"Neptune's Fortune" tells a story that begins with a bang and ends in relative silence. Give Julian Sancton credit for some voluminous research and a strong narrative. The "ghosts of the Spanish Empire" of the subtitle are brilliantly conveyed (hence the fourth star). But the history here is stronger than the shipwreck part.

Sancton, author of the creepily fascinating "Madness at the End of the Earth," has less to work with in this latest true-life adventure. The protagonist is obsessed to the point of near madness himself. He's an underdog who is easy to believe in. It's just that he has a really hard time getting the right people to believe in the same way. Sancton spends years with the guy, lending a sympathetic ear to his troubles. Along the way, you'll find that discovering buried treasure is overwhelming in many more ways than one.

"Neptune's Fortune" packs a ton of detail in a readable narrative. It's just that real life can proceed too slowly to stay consistently compelling. Sancton brings the saga to the surface, but it's not always easy sailing for the reader.

[Zandt McCue · Rating 5 out of 5]

Julian Sancton’s Neptune’s Fortune was an absolute pleasure to read. As a huge fan of his first work, I came into this book already knowing that his style of writing and approach to history were exactly what I look for—and this one did not disappoint. It had everything you could ask for in a great work of narrative history: meticulous research, gripping storytelling, and a cast of characters brought vividly to life.

By the end, I found myself deeply invested in the fate of Dooley. His story pulled me in so completely that I was genuinely concerned about how things would turn out for him. Some people live the most fascinating, unpredictable lives, and Dooley is one of those rare figures who seems larger than life yet entirely real. He is an extremely enchanting man, and Sancton captures that energy perfectly.

This is history at its most compelling—an adventure that feels both deeply human and endlessly intriguing. For readers who love history told with heart, drama, and an eye for the extraordinary, Neptune’s Fortune is everything you could hope for.
