The Merman King's Miracle Nanny

Dying of cancer, Mira awakens a half-blood mermaid. Six months to care for the royal cubs and keep them alive—or be erased. With modern parenting, she saves two princes, ends a ritual, and wins the merman king's heart. When a coup and beast threaten the Six Seas, she and the cubs fight back. She becomes mermaid history's first half-blood queen.
