Ok, so I've been rereading the Ring of Fire, mostly main series novels and a handful of my favorite side novels, and I remembered liking the Caribbean novels, but... I hate to say it, especially since this book ticks so many boxes of things I like in a book (naval battles, airships, alternate history) and it's part of a series I love, but this just isn't a very good book. First, basic synopsis is that after the events of 1636: Commander Cantrell in the West Indies, the Spanish have been knocked down a peg and the French have been removed from the equation entirely and the Allied USE, Danish, Dutch, and Irish along with various orphaned English colonies and indigenous tribes have established solid control of the Lesser Antilles. However, having bought time and space to push the Spanish back, the Allies proceed to do nothing. Despite having the technological advantage, and despite starting the novel by capturing the Spanish treasure fleet, putting immense pressure on both Spain and the Spanish new world colonies, they sit in port, get obsessed with internal political issues, and focus on building up their infrastructure wasting the opportunity to target the Spanish strongholds in Hispaniola and Cuba. And why do they do this? I honestly have no idea.
Their ships got repaired after the Battle of Vieques in the last book, they got reinforcements and resupply from home (not to mention all the ships and supplies they capture at the start of the book), yet they fail to take any offensive action for months even though it's made abundantly clear that time is NOT on their side. It's incredibly frustrating and the author never gives an adequate explanation why they're sitting on their heels and letting the Spanish take back the initiative and that's exactly what the Spanish do. For, despite being racist bigoted psychotic jerks without any future technology to speak of, the Spanish commanders are brimming with plans to push the Allies back, they seem to be able to pump out a ridiculous number of ships and new crews whenever they need them, and no matter how ridiculous their plans, the Allies just can't seem to stop falling headfirst into their traps making one wonder (AGAIN) why the Allies are just sitting around and doing nothing. It's almost like the author is deliberately slowing things down so the adversaries can play catch up. In fact, I'm pretty sure that's exactly what's going on here.
Now there are some good things in the story, subplot-wise, about the challenges of building up a proper naval base and the challenge of getting rid of slavery and the action (when it happens) is good, but there's also a bunch of subplots that drove me nuts like the ridiculous amount of time given to a romantic side-plot which is mostly held back because the people involved are being stupid or the ridiculous amount of this book taken up by listening to the Spaniards go on and on about how much they hate the heathens and patting each other on the back for being so clever and how if Spain's leaders ever finds out how the Spanish officers in the New World have ignored the rules, they'll all certainly die (yet these consequences are always just hot air, no Spanish characters are ever held to account for anything and there's no evidence other than their doom-saying that the Spanish government would react according to their fears, which is a clear failing of the authors: you can't just say "we're doomed so we HAVE to act this way" or "we're going behind our bosses' backs so we've GOT to all be together on this and we HAVE to succeed or we're dead" you have to SHOW someone being punished for such independent thinking and deviation from orders to prove this is a real threat, particularly as this is the excuse they give for doing unspeakable things which they claim to find personally repugnant; it makes them seem like hypocritical moral cowards). There's so many ways this could've been fixed. They could've cut back the Spanish parts and let us find out what the Spanish are up to the same way the protagonists do (and have allied spies fill in the necessary hints on Spanish schemes (and why isn't espionage more of a thing in this book, there's no lack of people in the Americas in the 17th century who would happily have devoted their lives and safety to see Spain brought low, yet only the Spaniards seem to have any sort of spy network)). They could've taken the effort to humanize the Spaniards by actually having some of them begin to question whether Spanish hegemony is sustainable or reasonable given how the world is changing. Better still, they could've had Spanish characters actually concluding that if they're ignoring Olivares's military orders, then for the sake of avoiding retribution in kind (not to mention their honor), perhaps they ought to back away from massacring Allied civilians. But no, they're just stupid arrogant pricks. By the end of the book, I just skipped any part from one of the Spanish perspectives and I don't feel like I missed much by doing so.
Then there's the murder, a secondary antagonist kills another secondary character, it's probably an accident (and thus technically manslaughter, I suppose) though still an action taken with violent intent, but they KNOW who did it, they know HOW it happened, and the victim was a noble (and the widow of the dead admiral of the USE task force, you know, the people keeping the Spanish from murdering them all). YET THEY DO NOTHING. Even though rounding up the guilty party (who ISN'T a noble and is a real jerk) and executing them would actually solve another problem (letting the big slaveholders know that they are not above the law, which for some reason, the characters keep acting like they are, letting them do things that would get anyone else hung by the neck until dead). It's insane. Even in the Ring of Fire universe, you can't just go around murdering nobility and expecting to walk away Scot-free, there would be royal decrees from above demanding retribution regardless of local political expediency. It doesn't work, it's just stupid forced drama.
Don't get me started on the ridiculous plan the Spaniards come up with at the end of the book which (despite being utterly insane) sort of works (because the Allies act stupid, again ("Oh no, the enemy ships are escaping into that lagoon! We have to follow!" IT'S A LAGOON, YOU CAN JUST WAIT AT THE ENTRANCE AND THEY'RE STUCK IN THERE, YOU MORONS... ahem)) until the Spanish remember that the Allies have guns that can annihilate them at ridiculous ranges and realize they have no chance (and never did). Then, somehow, despite having the slower and less powerful ships which DON'T have steam engines so they can maneuver at will, they run away and live to fight another day... again. The author has a very BIG "I don't want to kill off the antagonists" problem, and he proves this by not only letting the Spanish commander once again slip away when he should be dead to rights, but by literally bringing a presumably dead antagonist from the first book back from the dead just so he can wax malevolently about his evil plans (insert annoyed eye roll). This book is huge, something like 700 pages, and when you stand back and look at it from a distance, the plot progress is glacial, at best. Barely any changes are made, territorially or politically, the main factions are all basically the same at the beginning and the end, and none of the major antagonist characters are killed off. Worse, the book ends with a whole lot of sequel-baiting for books that probably will never be written. Sigh... All in all, this is a pair of authors I KNOW can do better than this (both alone and in combination), and the whole book just feels like they were too invested in trying to build up the stakes rather than having the various parties act intelligently, and it feels off, and given the situation the series is in post Eric Flint's death, this book feels like a wasted opportunity. The Ring of Fire series was at its best when it embraced crazy energetic dynamic events turning the world upside down not slow plodding drama and this book is two mildly interesting events sandwiching 600 pages of largely inconsequential drama at the end of which the main character leaves because there's actually important things going on and wouldn't you know it, it has nothing to do with anything that happened in this book.
