Lost Heir by Karina Espinosa

In the stunning sequel to the fantasy romance Blood Weaver, Leila—revealed to be Princess Lyanna of Valoria—faces new trials and deceptions. After escaping the harsh realities of the Central Plains, she returns to her homeland with Prince Caelan of Eldwain and Ronan, a hostage from the fearsome Crimson Clan of the Grasslands. But peace is fragile; the king of Valoria, seeking to avoid a war, commands the release of Ronan.
Now free, Ronan confronts Lyanna, begging forgiveness for deceiving her and unraveling truths that shake the very foundations of her beliefs. As they navigate their complicated feelings, a grand banquet hosted by Lyanna’s father draws not only dignitaries from across Asteria but also uninvited dangers. Shadows from within their own ranks threaten to turn the festive occasion into a nightmare.
Amidst these swirling conspiracies, Ronan and Leila must discover whether they can trust each other enough to confront what lies ahead. As the prophecy looms over them, their choices could save their lands—or lead them to ruin. Will the truths they uncover allow them to stand together, or is their fate already sealed?
