Sea Change: A Novel
BENEATH THE CALM SURFACE A DEADLY TERROR AWAITS.
In the cold waters of the Pacific Northwest, two fishermen are the first to feel the heat. Then a young girl, playing innocently by the seashore--before dying an agonizing death. Now the media have a story. Reporters, scientists, and government officials are descending on the coastline, searching for a killer in the water. Renegade oceanographer Brock Garner is at the center of the storm.
He wants to know why he's finding dead zones in the Pacific...and why his best friend's heart stopped after he examined ravaged sea lions on a beach. Dr. Ellie Bridges, on duty when the little girl died, has questions of her own. Thrown together in the chaos, Brock and Ellie are about to uncover some disturbing about a catastrophe of unimaginable proportions that is growing. Gathering strength. And moving--unless they can stop it--south toward a new victim. Seattle.

I’ve always been fascinated with story that take place on or under the oceans and seas. This doesn’t disappoint. The author weaves sci-fi, horror, and thrillers aspects to create an intriguing and compelling story of watery disaster.

7.5/10
Let's talk about this book... this book sure feels long but only has 450 pages. The problem with it is that they took to long to get anywhere and sometimes it drags in some places.
The story is set near canada\usa border near Seattle. Something is killing animals and people. Nobody knows what it is, some kind of weird water phenomenon. Enter our main protagonist and ex military and now turn environmentalist, divorcee and now roaming the waters with his crew. Meanwhile his ex-wife who knows of his knowledge contacts him and with the help of money from her now-husband they track down the culprit.
It's not that easy, you've got other characters like a medic who treated two people who died plus a bunch of others side characters that are there to help our main protagonist.
I learn a lot reading this novel, from pfiesteria to plankton to other stuff related to the sea. I think since James is a marine biologist he knows his stuff and tried to set the story within people who are not versed in marine biology but at times it enter the realm of science which was interesting since it made me search for stuff.
There are some interesting parts, this thing than can kill humans (and it seems it exists) but taken to extreme, the author at times it seems it gave it a personality/intelligence that I don't know they should have.
Either way, the vast majority of the book is the characters talking about possibilites, about plan of actions and at times we see the destructive power of this being. IT was interesting. As I said, it's slow and I can understand people don't like the novel, or why it has a minus that 4 rating. There is another novel very similar to this one called the Swarm written 3 or 4 years later. It was based on this one so you get to see similarities - the main issue for me is that it's a 900 page novel.
Either way, this is a good novel BUT be prepared for slow burn.

Well, I can see why this book has not got a lot of ratings love. Published in 2000, SC has an interesting premise, and with a different author, it might have been great. Our lead protagonist, Brock Garner, is a grad student studying plankton and so forth in the ocean off the coast of Seattle. Brock designed a new tool-- medusa-- which is basically a mechanical devise that is dragged behind a ship and samples the water for all kinds of things. You will read in almost painful detail all the things it can do. Anyway, the book opens with several people dying strangely-- their bodies basically dissolve from the inside out or their skin basically melts, etc. Kinda gruesome, but so be it.
With a lot of preamble, it turns out that there is a type of virus/organism/microbe that has formed a major 'slick' in the ocean off the coast and it releases a toxic aerosol that kills you quick; worse, if the virus thingie comes into contact with your skin, it basically eats you alive. Sounds great, no? Well, it could have been at least a decent thriller, but the excessive, obtuse scientific descriptions of everything, the clunky dialogue, the stereotypical characters and the slow unfolding of the plot (never mind the horrible romance and a female lead who really needs/wants a 'real man') barely kept me interested enough to finish it. I am not sure what audience Powlik was aiming for here. SC is way to technical and slow for a 'beach read' type thriller; horror readers will be bored even given the nasty 'slick' of man-eating microbes. This kinda turns toward the end into an action thriller as Brock, with some 'on the sly' help from the US Navy seek to isolate the slick and kill it. The epilogue was just icing on this cheesy pile. All in all, SC one best to avoid unless you are really bored and stranded on an island somewhere with nothing else to read.
I believe Powlik has a best seller before this one, but if this did not tank his writing career I would be amazed. 1.5 rotten tomatoes.

Thrillers with an oceanic twist invariably end up being amongst my favorite. It’s an admittedly small sub-genre and one that I greatly enjoy. Powlik’s addition to the sub-genre is a thrilling one. The plot holds plenty of excitement and the characters come to life above the stock-character genre level. There’s a definite effort here to give it a solidly scientific tone with a strong attention to detail - which unfortunately can slow the overall pacing down at times. There is one major, gaping hole in the plot regarding this Pfisteria, but it sounds like Powlik’s second book, Meltdown, is a sequel, so hopefully these loose ends will be addressed. All in all, it’s a fun read with entertaining characters and an exciting storyline. I definitely enjoyed Frank Schatzing’s The Swarm, more, but Powlik’s novel is a lot stronger than Dave Freedman’s Natural Selection. I definitely plan on keeping my eye out for the sequel!

This is a pretty good thriller involving some deadly plankton blossoms in the sea that may or may not have been created by man and the deadly tide of these microscopic killers are getting closer and closer to Seattle!
The plot was pretty good, there is a lot of science in this book and I found most of it very interesting but it also tended to bog the story down at times.
I didn't like the two main female leads very much at all, Carol seemed to be in a rage most of the time I began to doubt if the woman was even capable of ever having a normal conversation, most of the ones she had that were directed at her husband, father and ex husband were rants and Ellie, the other main female character seemed to me to be to wishy washy and a little cold emotionally.
I liked the main character Brock and the description of the setting was both beautiful and wonderfully detailed.

I read this book quite a long time ago, but it has stuck in my mind and obviously passed the test of time. I loved that it is set in the Pacific Northwest, and I found the story to be very engrossing, even though I'm not a "sciencey" person, I was able to catch the gist of what was going on. I think I'll give this book a re read this summer.

This has been in my to-read collection since about 2000. That means I have moved this book no less than six times. I wish I had lost it at some point.
This was dreadful.
I don't ever expect a late 90s/early aughts bio-techno-thriller to be great literature, but I do expect it to be fun. Entertaining. This was not. It was a too-long slog that was a struggle to finish.
It was about 200 pages too long, with characters that barely have any kind of impact or personality. In fact, the author seems to recognize that when, in the last 70ish pages a main character dies and no one reacts to it, another nameless person gets DECAPITATED and a character remarks that their name didn't even matter, and another person just falls out of a helicopter. Also, two characters have an awkward, quick, poorly written sex scene with about 40 pages left...the pacing of this is terrible.
The science could be interesting, but the passages are long, repetitive, and worse than reading a textbook.
I will say the early death scenes are entertainingly gruesome. That's about it for redemption.

For starters it was really well written, super informative on the true science bits but written in a way non-sciencefolk (me!) can understand. Plot of the mysterious pfisteria outbreak in the water killing people was fascinating, it made me want to research after and see if something like this is possible. Truly my main qualm lays in the weird and rushed relationship between Dr. Ellie and Brock. It felt unnecessary to the story and didn’t build to anything, it just felt the author had to reach a word count so he through in this strange plot aspect. My other qualm was there seemed to be no resolution to how the outbreak started. I think the author tried using the epilogue to explain how it can be spread but the story never actually finished the story line of it being originally manufactured as warfare. Overall I would say this is a 4/5, well written, fascinating and I couldn’t put it down.

I absolutely loved this book. So much so that I'm in the process of tracking down the other 3 Powlik books. If I had to describe this one, I would say that this book is closer to a Douglas Preston & Lincoln Child book mixed in with a dash of Ebola by William Close - Glenn Close's father's (nonfiction) account of his time treating Ebola in Zaire in the '70s. Granted, Powlik's book is very much fiction, but it's incredibly plausible - genetically modified dinoflagellates that have been released into the ocean and are causing widespread death. It's heavy sci-fi horror. Quite frankly, it's everything that I've been missing in a lot of the more modern horror books. I absolutely devoured it.

Definitely one of the best books I read this year.
The writing style is to the point while still providing enough descriptions to really get a feel for the scene and the characters. Even the characters that only show up for a chapter are well rounded enough to care about them instantly.
The descriptions of the images in the horrific scenes these characters experience & come across is fantastic - the magnitude of the situation and the horrific deaths so many are suffering really comes across and hits you hard.

i was excited about this book
until
I got into it. I thought there was going to be a monster not a biological weapon. it had some interesting comments. My favorite was the one about the guy with the bug up his butt. I guess this could be scary because theres no telling what the Government is doing in some of their labs. There a glossary at the back of the book to help explain the terms used. When you need to read a dictionary along with s book to understand it then the book is too complicated for pure enjoyment t. When is becomes a text book its not worth reading.

Started out a bit too violent but then turned into a pretty good book. A bit extreme at times dealing with "practical* things. Navy would never send in a sub to destroy a civilian ship. Good storyline.

This 1999 yarn by James Powlik came to my attention in a used book store. It is a riveting yarn pitting marine biologist/oceaonograper Brock Garner against a deadly colony of rare phytoplankton previously unknown to science.The setting is the Pacific Northwest, BC and Washington State.Brock is doing his Ph.D. thesis at the Bamfield Marine Station on Vancouver Island. When the novel opens Brock is at sea in the middle of the Pacific on a research vessel monitoring plankton and oceanographic parameters with his own novel towed monitor. Meanwhile back on Vancouver Island Ellie Bridges, a doctor in the ER at Port Alberni encounters several patients who turn up with weird symptoms and quickly die. Brock's friend Mark Junker who is investigating sea lions finds some badly dissolved carcasses. He quickly develops similar symptoms and ends up dead. Brock is summoned back from the ship to attend his friend's funeral. From there he is thrown into a maelstrom as he tries to track down the cause of the deaths and once he figures out what is happening by default he is thrust into leadership of the fight to bring the rampaging biological menace to heel.
Fastpaced, pageturner.

I didn’t really dislike this book, but I didn’t much enjoy it either. The story is definitely the draw for this book. The characters are flat and very uninteresting which robs the story of some of its power. Several characters meet gruesome deaths, but because they were unappealing, flat and boring, I didn’t care. A reviewer called this book “an expert riff on the classic monster-horror novel,” and I’d have to agree. And while the story is pretty interesting, it would have been much more powerful, much *scarier* if the characters had been more developed.
Characterization is almost nonexistent; Cardboard cutout characters
Possible Read-A-Likes: Thrillers by Preston & Child; The hunt for Red October by Tom Clancy (although Clancy's book is much better written.)

I still can't decide:
Was this one "Sea Change" inspired by "Der Schwarm" from Schätzing - or, more likely, was the "Schwarm" inspired by this one.
They're just TOO similar.
It's not as bombastic. You could say: It's the Swarm without tsunamis and a bit more well-grounded biology.
The characters are as cheesy as Schätzings but thankfuly it's a good deal shorter and therefore cut out most of that greasy pathos, that Schätzing has quite overdone.
Additionally, Powlik is an actual biologist (maritime biologist at that) and not an advertiser like Schätzing (or me. *g*). That just might be the reason for the better book (this one) not being as successful as "The Swarm" by far. *g*
A nice re-read, on the whole, when you re-read all those hundreds of other books on the shelf. ;)

This novel is set in the Pacific Northwest, where people and marine mammals are dying after being exposed to something in the water that destroys them. The main characters are a marine microbiologist and his ex-wife, a whale sonar expert, and a doctor who treated some of the victims. The race to identify and neutralize the killer before it decimates the population in the Seattle area is complicated by an oncoming storm and the interference by other interested parties...don't want to give it away, but there is plenty of intrigue and technical detail to keep it interesting.

This book is hard reading...I have a very strong science background and even that didn't help with much of the terminology. This is the first work of fiction I've ever read that required a glossary. I think so much more could have been done with this topic. The author spends more time describing the ships and the gear than he does developing his plot. Not really a fan of this one and won't be reading any more from James Powlik anytime soon.

Thought this one started slow, but had a good ending. Didn't like that there was a map, but many places flagged in the story weren't on the map. Plus didn't like that everything kept getting flagged in latitude and longitude and again, wasn't on the map. Silly complaint I'm sure, but found it mildly distracting.
April 21, 2009
This suffers from what so many thrillers suffer from, tremendous buildup and an anticlimatic ending. Once I knew what was killing everyone I was thinking to myself, why don't they just go kill it? Go blow it up or something! That was 2/3 of the way through the book. Wanna guess how it ends?

The prolog and the epilog were the best. The stuff in between was good, technical at times but good. I really enjoyed this book as I thought it was all figured out until the epilog!!
January 6, 2009
I really like it. Thought it was imaginative, creative and the possibilities scary. I could be biased because it's locally based, but science/tech books take me on adventures.

Suspenseful tale of bioterrorism/red tide in the Puget Sound area.

I couldn't finish this book. The story itself is quite interesting but Powlik stuffed this book so full of technical details and biologic explanations that it confused me more than it helped me.
July 26, 2011
Great pace...very scie tific...learned a lot!

Takes a little bit to get going but once it does, it is super engaging.
And now I know a lot more about oceanic studies and terminology so that's a plus too !
