Okay, so the Costa Leona series situation is a bit messy right now, and I think that's honestly part of the reason it's getting so much buzz in the indie fantasy circles. As of this moment, I'm pretty sure there are four main published novels that are universally agreed to be core: 'The Gilded Cage,' 'Shadows of the Sun Palace,' 'The Silent Siren's Debt,' and the most recent one, 'A Crown of Ashes and Embers.'
But then you've got the spin-off novella 'Tides of a Forgotten Harbor,' which the author insists is a companion piece but not essential for the main arc. Some fans include it in the count, others don't. The author's newsletter also hinted at a fifth book, 'Veil of the Sapphire Coast,' being in the final editing stages, but it's not available for purchase yet.
So, your total depends on how strict you want to be. For a complete story so far, it's four. If you're collecting everything set in that world, it's five. I'm waiting for 'Veil' to drop before I do my next series re-read.

Man, I wish there were a concrete answer on this one. I've been scouring the author's socials and publisher updates for months, and it's radio silence. The last book, 'The Gilded Cage', came out what feels like ages ago, and that ending was a massive cliffhanger! You'd think there'd be at least a working title or a tentative release window by now.
Part of me wonders if the series is just on a longer hiatus. The world-building got incredibly dense by the third installment, and maybe the author is taking time to map everything out properly. I'm trying to be patient, but my book club is starting to get antsy. We keep checking the usual pre-order sites, but nada.
Honestly, I'm half-tempted to just re-read the old ones and look for foreshadowing I missed the first time around.

Let's be real, this one gets weird even by 'Costa Leona' standards. So after the whole asteroid-mining consortium collapse in Series 13, Series 14, 'The Gilded Abyss,' jumps forward a generation. The main plot follows Elara Vance—granddaughter of the original terraforming director—who's basically a bureaucratic archivist stuck cataloging the failing ecological domes. She stumbles on evidence that the supposed 'accidental' depressurization that killed her family was a cover-up by the remaining corporate cartel.
It's less of a straight adventure and more of a slow-burn conspiracy thriller inside a decaying biosphere. Half the book is her trying to convince anyone in authority while dealing with atmospheric scrubbers failing and strange fungal blooms spreading in the lower agricultural levels. The corporate antagonists aren't cartoon villains; they're just desperately trying to keep the profit machine running as the whole colony falls apart around them. The ending is brutally ambiguous—she gets the truth out, but the system is so broken it hardly matters. Felt very different from the more optimistic early books.
Not my favorite in the series, honestly. The pacing drags in the middle with too much detail about the archive systems.

Okay, so the Costa Leona series. That first book is 'The Edge of the Sea' by Marion Harmon. I almost passed it over because the title made me think it was just coastal nature writing, but it's actually this great political fantasy set in this fictional Mediterranean-esque kingdom.
It absolutely works as a starting point. You get dropped right into the palace intrigue with Elara, the queen's spymistress, as she's trying to uncover a conspiracy. The world-building doesn't feel like an info dump; you learn about the magic system and the rival noble houses through the plot. I picked it up on a whim from a library shelf and got hooked, finished it in two days.
Some lists might suggest starting with the prequel novella, but honestly, you can skip that and go straight to 'The Edge of the Sea'. The main story stands alone perfectly.
