Mermaid Princess Amelia – Best Mermaid Book Series For Teenagers

Queen Macy Jakobson is a usurper who rules the Scotia Sea, a region in the Antarctic. She is described as paranoid, a trait that Jet Mir finds useful for identifying potential problems during his mission to find the Tierra del Fuego treasure. Jet Mir falls ill in the Bellingshausen Sea and is treated by Macy and her assistant Harriet Rebane (a former assassin). Despite her dark past—she is explicitly called a usurper—Macy is a valuable ally in Jet Mir’s quest. She and her family are known as a dynasty of usurpers and murderers, yet Jet Mir is pragmatic enough to ally with them for strategic gain. Macy has no dialogue and no on‑page presence; she is a figure from Jet Mir’s letters, a morally compromised queen whose paranoia makes her both dangerous and useful.
