Master the System. Survive a vast and unfamiliar ocean.

Thankfully, that isn't the end for him.
He wakes up alive and healthy. And he has... tentacles.
...What?
Follow Henry, a small Trickster Octopus trying to survive in a vast and unfamiliar ocean.

This book is AwesomeSauce! I loved it too pieces!
I'm always a sucker when it comes to a MC that's been Reborn into som'min that's not human. Whether it be an Ant 🐜, a Dragon, or even a lowly Blue Slime. I could name others but you get the picture, Right? In this tale our MC is a very small Octopus 🐙 struggling to get a bite, a meal that isn't gonna turn the table and eat him instead. And thus begins Henry's monster life. And with an AI that gave him an incouraging word a pat on the back and an admonishment to not die, before cutting him loose and then swimming away!?! 😆! So Henry worked on a plan to do just that, and leveling to get stronger. It wasn't until he met the Whale Pod to realize that there were other sentient beings sharing the ocean he lived in. He made a friend, Maurice a chimeric crab and together they went off on a grand adventure to grind, level and look for more friends. And maybe just maybe we'll find out if Ash is friend or foe.
So yeah grab some sushi, get the book or better yet audiobook to enjoy Henry and Maurice's great adventure!

Too fast
The advancement through the levels was too fast. Not enough time was spent on character development. Too many fights were essentially, 'and then Henry won.' There were some good fights, but...
To the good: fast moving plot. Setups for future installments. A comic relief sidekick that was actually funny sometimes. In summation: Needs work, but good enough to read the next one. Tom out

The fast progression was what really stood out to me about this book. The plot is engaging with there being some very fun interactions between Henry and his crab friend Maurice! I will say that I didn’t quite get what was happening at the end with Ash, but nevertheless I liked her POV sections as well.

A nice slice of epic under the sea cultivation adventure
I found one of the authors other works interesting and decided to check this one out. Glad I did as it was a great under the sea cultivation tale.

Great Read
This was a pretty good imaginative take on an iseaki/reincarnation genre. I enjoyed how the System and levels got gained. But the introduction of the human characters just seemed kinda thrown in.

Fun funny and good action
The premise was interesting The book had good humor and action sequences as well as character introspection and growth. Absolutely waiting for book two to drop.

Wonderful world building and amazing characters

This is pretty fun, although it starts to drag when he's sitting about crunching numbers in the middle. It reminded me of Octogeddon, by George Fan, quite a lot, actually. Swapping the arms out and stuff.

He went from studying marine life to being marine life. I loved how he was about to modify himself and his crabby companion to make them stronger and tougher so they could survive.
Did Not Finish
August 10, 2026Interesting concept, and I got over halfway through it, but it started to feel like there was too much moralizing and existential dread in the back half.
