The Girl of Ink and Stars

On an island whose Governor forbids anyone from leaving, Isabella's father keeps the old maps hidden — charts that name rivers and mountains beyond the wall, places the authorities have declared don't exist. When her best friend disappears into the Forgotten Territories, Isabella follows, using her father's cartography as both guide and talisman. Hargrave draws her fictional island's spirit from the maps that Portuguese navigators produced in Lisbon's Casa da Índia during the fifteenth and sixteenth centuries — instruments of curiosity made dangerous by the people who wanted the world kept unknown.
