The Lure of Fire (The Elemental Series) by Chloe O'Connor

Upon turning twenty-one, I reached the required age. The magic number that would grant me entry to the hallowed gates of the Academy of Elements where I would learn to control my gift as a waterborne fae.
Six arduous months of relentless training and exhaustive studies awaited, all in preparation for the impending battle with power-hungry humans and their ongoing century-old war.
Little did I know, my life would irrevocably change the moment I crossed the academy's threshold. Now I’m drowning in lies and burning with a passion for a man I can’t deny.
Everything I thought I knew about who I was, and what is expected of me, unveils a life I never dreamed. Setting me on a path of destiny and adventure beyond my wildest dreams, sealing my fate with the last person I expected.

Mythical Guardians are just that, mythical... or are they?
