Drowned Steel

by Cameron Coral

Robots are walking into the ocean. Nobody knows why.

Block and Wally race to the Oregon coast after a distress call comes from Cybel—robots are marching into the waves, obeying a signal hidden in whale songs. The a military weapon buried forty meters beneath the bay.

Cybel can track the weapon’s signal, but salvagers loom. Block the CleanerBot struggles to protect the settlement. Only Wally's rewired neural pathways can answer the corrupted song with something the whales—and the robots—can finally hear.

Drowned Steel is a hopepunk, post-apocalyptic adventure about found family, misfit robots, and choosing who you become when the old world is gone.

Book 3 in the Robots and Ruins series—robot fiction for adults who want hope with their survival stories. Perfect for fans of Martha Wells, Isaac Asimov, Becky Chambers, and Adrian Tchaikovsky.

332 pages, Kindle Edition

About the author

Cameron Coral writes hopeful science fiction about robots who are trying their best, even when the world rejects them. Her novel Steel Guardian, about a post-apocalyptic CleanerBot, took second place in Hugh Howey's 2021 science fiction novel competition, the SPSFC, and launched the six-book Rusted Wasteland series.

She lives with her husband on an Illinois prairie surrounded by trees, where the household is ruled by Marty the Jack Russell terrier. Her neighbors include more than a few wild turkeys and one very introverted groundhog. When she’s not writing, she’s attending plays and concerts, volunteering, and enjoying lemon cookies from the local farmers' market.

Another great adventure for Steel and Wally as they travel to help Cybel and Oxford with a serious problem. They find themselves in danger in more ways than one. An excellent storyline with plenty of action throughout. A must read. I received an advance review copy and I am leaving this review voluntarily.

Drowned Steel is a thoughtful and imaginative post-apocalyptic adventure that blends science fiction, mystery, and hope into a story that is both exciting and emotionally rewarding. Cameron Coral continues to expand the Robots and Ruins series with a premise that immediately captures the imagination: robots mysteriously marching into the ocean, drawn by a signal hidden within whale songs.

What stood out most is the originality of the central mystery. The connection between artificial intelligence, marine life, and a forgotten military weapon creates a fresh science fiction concept that unfolds with steady suspense while raising deeper questions about technology, communication, and purpose.

The relationship between Block and Wally remains the emotional heart of the story. Their loyalty, resilience, and willingness to protect others reinforce the novel's hopepunk spirit, proving that compassion and cooperation can survive even after civilization has fallen. The idea that Wally's unique neural pathways may hold the key to breaking the corrupted signal adds both emotional and narrative weight to the adventure.

The worldbuilding is another major strength. The flooded landscapes, struggling settlements, and evolving robot society feel immersive without overwhelming the reader, creating a setting that is both dangerous and filled with possibility.

Drowned Steel delivers a satisfying combination of mystery, action, heart, and optimism. Readers who enjoy intelligent robot fiction, found-family stories, and hopeful post-apocalyptic adventures will find this to be a memorable and uplifting addition to the series.

Drowned Steel is the third book in the Robots & Ruins post-apocalyptic sci-fi series about a quietly heroic CleanerBot called Block and his adopted human daughter Wally, now a teenager. This series is a continuation of the Rusted Wasteland chronicles, but you don’t need to have read those to enjoy this one which is a standalone adventure.

Block and Wally have left their peaceful Minnesota settlement of Deer Valley to visit their friends Oxford and Cybel at Cascade Haven on the Pacific Coast, in the hope that Wally’s newly discovered abilities will help them understand a mysterious signal emanating from the ocean that is driving robots to throw themselves into the salt water that is deadly to their circuits. They arrive to find that the mistrustful mayor of the human village nearby is planning an attack that he hopes will drive the robots away. With time running out and tempers fraying, can Block and his friends save everyone?

I really enjoyed this instalment which had it all - intrigue, action, suspense, politics and even a little romance. We get reacquainted with characters from the earlier books, like Cybel the TrackerBot turned protector, as well as meeting new ones, human robot, and canine! You know with this author you’re going to get feelgood moments and a happy ending, hope, humour and pathos. The relationships between the characters continue to evolve and I look forward to finding out what happens next.

Thanks to Cameron for the ARC. Drowned Steel is available now.

****SPOILERS***

I have read all the books in this series as well The Rusted Wasteland series. I have enjoyed all of them. This book though? Meh, not so much. I looked forward to the ongoing story of Wally (and introduction of Marty) and Block. Most of it was good but the story quickly fell into the realm of unbelievable. Something about Wally's ability to communicate with animals, a system that was being broadcast using whale songs that caused robots to walk into the ocean. Then Wally's humming a song that changed this dangerous system and created a new song for whales to carry and save the robots??? It turned into a hot mess that just didn't make any sense at all. Maybe to the author this all made perfect sense, but that didn't translate to the story, at least not for me.

Cameron Coral is one of my favourite authors and I love blocks story
But this time I hate to say it; it’s one of my lesser favourite books in the whole series
It didn’t glue my attention as much as the rest
I was disappointed that it took me longer to finish it than the rest of the rusted wasteland books and the drowned steel books
I really hope the next one to be better

This is probably Cameron Coral’s best book yet in the series. Set mostly on the Pacific coast, the action involves on- and below-water action. The characters are good and a new main human character adds a nice new element.

Drowned Steel Delivers Another Great Adventure - book 3 if Robots & Ruins

Wally, Block, Cybel Venatrix, and Oxford deliver a delightful new adventure and young love blooms in a story that kept my attention from start to finish! I never want this series to end!

Spoiler alert, did not like the way the author changed walley

I really don't know why they think adding in peoples sexual preferences is needed in a book that kids could read! This is why I only gave 2 stars. Please don't continue to add in this type of context.

Good entertaining story featuring Block and Wally. Characters are dynamic and well rounded. Decent Young Adult fiction.
