Princess of Rubies — Amy Richie

Sixteen-year-old Stella's world is turned upside down when she discovers mermaids are real-and she might be one. With no one to turn to and only a cryptic message from her missing mother, Stella embarks on an underwater journey like no other. She's guided by Draven, a mysterious and enigmatic mermaid who promises to help her find the truth. Together, they dive deeper into the ocean's secrets, heading toward the Red City-a place where danger and revelations await at every turn. But the deeper Stella goes, the more she questions: What if the truth about her identity is darker than she ever imagined?
