Find That Book

I'm trying to find a novel that I read on Wattpad within the last 3 years, although it could have been written earlier. It's a combination of fantasy, chicklit, ya fiction, romance, and adventure. The female protagonist is a princess (or some type of royalty) in her late teens or early twenties and has the ability to manipulate/bend water. Her powers can be dangerous and hard to control at times, which is a plot point that jumpstarts the novel. She accidentally kills someone at the beginning of the novel which leads to her running away and joining a group of pirates. They go on a series of adventures that build up to a massive battle at the end. The pirates don't like her at first but they grow close and she becomes part of the crew. She and the pirate captain - whose name I'm pretty sure is Gideon but I could be wrong - fall in love along the way. It's one of those will they-won't they situations and one where their feelings are obvious to everyone around them. One of the plot points includes them searching for a magical ring or similar object connected to the female protagonist's powers/some ancient force. Ending scene includes a battle with plot twist (included at bottom of post)

Other random details:
- The author started a sequel that I remember having a reddish orange cover and was more fire based/had fire as a plot point (as opposed to the blueish cover/water based plot of the first book), but then discontinued writing it because of writer's block or a similar issue. She never said anything that I can remember about taking the books down, so the first one at least should still be up.
- the female protagonist's mother is dead and her father remarried. I'm pretty sure the stepmother ends up being the big bad but I could be wrong.
- Gideon/the pirate captain has a tragic past that includes a dead fiancée (I think she died in a fire? which might have influenced the second book)
- there's a scene in the book where the female protagonist and Gideon are alone, somewhere on an island or a beach. She touches an ancient sword/magical object (it might have been the one they were looking for) and blacks out/has a vision. She wakes up to Gideon holding her to his chest, thinking she's dead
- I vaguely remember the main character cutting off her hair/having to disguise herself as a man to hide in an army

- at the end of the novel, the female main character and Gideon end up fighting the big bad. AND ***SPOILERS*** IN A MAJOR PLOT TWIST (at least to me, I totally didn't see this coming)










Gideon betrays the female protagonist, in a move related to his past trauma. The main character was trying to persuade him to either kill or not kill the villain, or something like that. He does the opposite of what she whats him to do, despite loving her and having gone through so much. It was a really upsetting moment for the characters and the second novel picks up immediately afterwards.

Thanks in advance for any help!
