Lady of Dragons (Part One)

Why these tropes fit

A childhood-friends-to-lovers arc anchors a high-fantasy quest in which a strong-willed heroine bound by soul-fate to a dragon (a fated-mates bond) discovers she now wields the very magic her knightly order is sworn to destroy—forcing a hidden-identity reckoning. She must weigh the ultimate sacrifice of her knighthood dreams and her romantic future with her sweet childhood-friend love interest against saving a beloved dragon, all while standing against a dragon-killing monarchy.
