Insanely Radiant

Radiana didn't want to die. Offered as a sacrifice to the sun prince in place of her scheming half sister, she decided to do whatever it takes to survive... but never dreamed it would be in the bed of the sun prince! Oratio is sick and tired of receiving human sacrifices. A disillusioned sun prince with the ability to read minds, Oratio involuntarily rescues Radiana from the burning altar...and is shocked to see that she can meet his eyes without bursting into flames. His interest piqued, Oratio offers to let Radiana live... by spending a passionate night in his arms, but Radiana would rather die than go to his bed willingly. Unbeknownst to them, however, there are forces that will stop at nothing to break them apart. Will Oratio and Radiana realize they're meant to be together... before their enemies come to break them apart?
