The Alpha King's Secret Heir

Lowborn rabbit-hybrid Evelyn spends one wild night with Kaleb, the feral Supreme Alpha, and bears his pup. To save her son, she abandons him at the castle, then returns disguised as his nanny—the only one who can soothe the feral pup and the king. When the truth surfaces, Kaleb defies the elders, abolishes the blood caste, and crowns her his Luna.
