In the enchanted underwater City of Glass, what will you sacrifice for immortality? Love, memories, freedom? Will you take freedom from others to win your heart's desire? Dive into a world of mermaids, mermen, and other merfolk, where every character has secrets, and nothing is what it seems! The whales have granted the merfolk eternal life, and asked you for so little in return. Defense against the giant squid. Secrecy from humans. But when a rogue mermaid tries to destroy the gift of immortality, ancient secrets rise from the depths, and the delicate balance of society rests in your hands.
