TBH, I threw your description to chatgpt to see what it could make out of it, this is the response I got. Check to see it managed to get it right…
Based on the plot you provided, it sounds like you’re describing the “Grisha” trilogy by Leigh Bardugo, specifically the first book titled “Shadow and Bone.” The protagonist, Alina Starkov, possesses a dormant power known as the “Sun Summoner” which she discovers when she is aboard a flying ship called the Volcra. She has no memory of her childhood and embarks on a journey to harness her abilities. Along the way, she encounters a man named Mal who saves her when the ship is attacked. Throughout the series, Alina grapples with her identity and the choice between using her powers to save or destroy humanity, ultimately deciding to destroy magic itself. The series also features elements of a magical world, flying ships, and a dangerous wilderness filled with magic.
