what point of view would you want to see in my book series?

I'm asking myself loads of questions as I'm outlining this book series. It will definitely be the biggest writing project I will have done yet. Just the idea of writing three books in the same world, same plot, and story is terrifying but so exciting. I'm really intrigued by this story and I haven't read anything like it (well of course it has some similarities but still xD).

Here's the one-sentence plot and in the spoiler is the full plot (if you want to read it and don't want to be spoiled I recommend not opening the spoiler):

Sixteen-year-old human girl meets a young merman and discovers an entire civilization under the sea with a war against spreading evil or "black water".

Spoiler

In Book One (Black Water), we read about the sixteen-year-old demi-mermaid discovering an entire civilization (Atlantis) under the sea after encountering a merman prince. Not only does she fall in love with the prince when she knows she shouldn't, she discovers that the mer people are endangered by a spreading evil called "black water". Unable to be return to the land (WHY), the demi-mermaid struggles to find her place in the twisted mer court (there's a ball). Ends with her discovering the prophecy.

What point of view would you prefer to see?

If you like Sailor/Marina, I prefer Sailor.

Although I think Moira is the least obvious name (unless you're familiar with Gaelic baby names) ignoring the fact that I have a character named Moira so I might be biased

Names with secret foreign meanings are cool! (Except I first read it as Moria=LotR)

I'm with @BlueAfrica with this one in that both Sailor/Marina are my favorites out of the bunch.

edit

okay so for the main character I'm going to go with Marina. I'll change the poll in a minute to the next character if you guys want to help me by voting again (for a different character).

i'm not making a new thread because it's unnecessary and probably annoys people. i have so many poll threads >.<

I like Moira. It's less expected.

I'm a bit bummed out because I like the name Marina for the mc but I also like the name Marius for the prince. I don't love or hate any of these to be honest. Maybe that's because I haven't fully decided on the prince's personality and stuff.

Okay so Marina for the mc, Caspian for the prince. I don't need help with any of the other names so yeah. c: thanks for the help!

I actually decided to go with Sailor (but I might change it back to Marina later idk ahahahha).

In which case you could tooooootally go with Marius for the mermaid prince.

Although I was going to say "I love Caspian, but Narnia" except then I remembered Marius is in Les Mis, so whatever.

I actually like Caspian after outlining the character it seems to fit him better.

I mean I like Caspian but it makes me think of Narnia so Aegaeus and Cephas

And Marina is a reminder from like the Zigg and Sharko series.... So maybe go with Maria for the mermaid but the I making an ee sound?
