Warrior Princess by Karina Espinosa

In the fantastical realm of Asteria, where ancient bloodlines and magical allegiances govern the land, Leila, a blood mage with a complicated past, finds her fate intertwined with Ronan, the fierce warrior from the Crimson Clan. When an insidious plot by Prince Caelan of Eldwain threatens to destabilize all of Asteria, Leila must harness her formidable powers and confront secrets that could shatter the very foundations of her world.
Together, Leila and Ronan embark on a perilous journey through treacherous territories, from the Grasslands, Keldara, the Central Plains, to the deceptive courts of Eldwain, to safeguard their people and uphold ancient alliances. As battles rage and loyalties are tested, the pair must navigate a tapestry of intrigue and betrayal, where love may be their most powerful weapon or their ultimate undoing.

With the fate of Asteria hanging in the balance, Leila must decide if she can go against the man she once considered her best friend. In this epic tale of magic, love, and rebellion, only the strongest will survive to tell the tale of their victory—or their defeat.
