Vigloo

To save her dying Glacier Cat clan, orphan Sasha drugs Leo, the mightiest lion king of the grasslands, and steals his royal bloodline, falling pregnant with twins. In her womb, Kai’s fire and Nala’s ice keep raging out of control. Drawn by their scent, Leo closes in. Sasha means to flee, but goes into labor inside the palace—and a fire cub and an ice kitten wreck the room before his eyes.
