?Cori, Jem and Tarn travel to the isolated island of Halcyon to find the greaves, the leg armour that Cori needs to step into her power as Champion of Aquinta. However, as they arrive at Halcyon, they discover that the island is in fact an overgrown forest where sea water is at least ankle-deep, no one can grow any crops and everything belongs to the local wildlife. It’s a miserable swamp ruled by a corrupt Prime Councillor that the people of Halcyon can’t escape.

Cori and her friends decide to free Halcyon’s people and show them that there’s a better way of life away from the island. However, they must each complete a tricky trial to prove their good intentions. Will they be able to win the people’s trust? And will Cori find the piece of armour she desperately needs??

Oceanforged: The Sinking Ruins by Amelia Mellor
☀️☀️☀️⛅ (3.5 rounded up)

The latest book in the Oceanforged series finds Cori and her friends facing another hefty challenge when seeking out the next piece of armour. Halcyon is another isolated place hiding a secret - their ruler forbids all magic, controls knowledge of the outside world, and is wildly greedy with power. His whims lead to many unjust banishments and even deaths, which could be the gang's fate too if they don't defeat the trials.

Though the sneaking around and combat scenes were more visceral, I didn't find the tension quite so palpable in this book. Instead, the story was a bit more introspective for Cori, struggling with the weight of her title as Champion and what it means to be a saviour. This focus meant less growth for the supporting characters, but it still worked well without it. The eccentric ruler was an entertaining villain whose moral and ethical failings made for a good foil at the more drama end of things.

This series is a solid one, and I look forward to reading the next installment when it is released in the future. Cori and her friends have a few more items to collect and a ticking clock looming over them...


"It's really impressive that your dream is to go into politics someday. With the right preparation, I'm sure you could do a lot of good. But be honest. If you weren't the Champion, wouldn't you want your leader to be the best person for the job, instead of whoever had the responsibility thrown at them because they stumbled on some old artifices?"

This novel (paperback) was published in Australia end of July 2026 but the edition can not be found on Goodreads.

A fun and adventurous third book in the Oceanforged series!

Cori, Tarn and Jem set off to find another piece of the legendary Oceanforged Armour, leading them to the mysterious island of Halcyon.

Halcyon had changed since the Age of Glory and much of the beautiful glass city is drowning in water. A ruthless leader is determined to control magic and Cori needs to hide the gauntlet and hauberk whilst keeping her friends, Jem and Tarn safe.

Another exciting instalment in this five series adventure with great characters, plenty of magic and a fast-moving plot.
