Johanna fidgeted in her uncomfortable stool, twirling her long brunette hair around and around her finger.

on her uncomfortable stool

She couldn't’t put her finger on it was something new

correction - couldn't - this sentence is a jumble. It could be one of two things:

'She couldn't put her finger on it; something was new.'

Or

'She couldn't put her finger on it, was something new?'

She had the sudden urge[s] that she had[/s] to do something.

don't overwrite it; sentences become clunky and forced. Don't write in such a passive voice - use of 'had' is a real killer of action and presence.

Years later [s]when she had grown older and [/s]had come to know this sense, she would wish she would have ran outside to the other side of the island and saw what was coming towards them for herself.

Years later tells us that she's grown - 'when she had grown older' is redundant - adjust the sentence accordingly. What would seeing the ships for herself have done? Nothing. She would still be a child and still be unaware of the significance of a fleet of ships. Also, the sentence implies that she doesn't or didn't know of the ships coming, and yet she finds out a paragraph later.

She rolled her eyes at Jake, whom always was the one who riled up others.

Ick, this sentence is clumsy and awkward. I suggest:

'She rolled her eyes at Jake. He always riled up the others.'

A little white schoolhouse embedded in a nest of green valley.

get rid of 'nest' or change valley to a plural - 'valleys'

The scene looked so peaceful, so welcoming, warm, and loving much the contrary of what it soon would be, a pile of rubble and burning wood.

There is such a thing as foreshadowing = when the author subtly hints at future events and there is such a thing as just telling us outright. Like you did.

I think you need to pick a style of narration - either you tell us the story or we see it through the character's eyes, which means getting rid of all the little hints that you know what's going to happen or how so and so would look back with regret etc etc - pick one and don't mix the two.

There are some harsh things I could say regarding the content and cliches but I'm going to give you the benefit of the doubt. It wasn't, in my opinion, a really engaging prologues, but then prologues of this length rarely are.

Hope that helped,
Cheers
