My editor has amusing concerns about the magic system Harmony is bound to but then, near the end, he goes "wait, you mean Harmony hacks magic to do what she subconsciously wants?" And yes, this is the magic system Harmony briefly has full access to.

Almost everything Harmony does is based in her feral, vaguely monstrous inner self and her moral compass.

She has very little conscious access to most of the things that make her quote unquote powerful.

And a MEGA character board arc that involves strange evolutions of her abilities.

The events at the end of the book will VASTLY impact her abilities going forward.

Harmony deals with;
Book 1/Vampirism
Book 2/Inexplicable magic
Book 3/Love and monsters
Book 4/Loss and hatred
Book 5/Public knowledge

It's going to be a bumpy ass ride.

Similarly, there are "character arcs" set in the Fae Noir books
1/Morality(Azura)
2/Love(Bailey)
3/Hate (Vanessa)
4/𝗠𝗼𝗿𝗮𝗹𝗶𝘁𝘆 𝘃𝘀. 𝗧𝗵𝗲 𝗻𝗲𝗲𝗱 𝗳𝗼𝗿 𝗵𝗶𝗱𝗶𝗻𝗴 𝗵𝗲𝗿 𝗶𝗱𝗲𝗻𝘁𝗶𝘁𝘆 (Azura)
5/Magic becoming public knowledge (Aabirah)

We've also penned in book 4&5 titles for Fae Noir

Book 4/
Veiled injustice
Book 5/
The unveiling

Strictly speaking, books 3, 4, & 5 are all essentially book 3 parts 1-3.

Yeah.

Book 5.

Unveiling (Aabirah)

As you might expect, there will be a LOT of different points of view from other characters within the verse.

Also,

Guardian Harmony 5 & Fae Noir 5 are essentially the same incident from different viewpoints.

Aaaand there will be HEAVY implications and foreshadowing for Red Hood Rising

Also, there are some titles in the planning stage that are related to, but not directly part of, the main storylines.

Veiled Noir:
Beyond the grave

Trickster Rising:
Father's Day

Trickster Rising:
Antiheroism

Yes, those are Frank and Rumpelstiltskin titles.

YES, Frank centric books are fan requests.
