The Mermaid by Christina HenryRead about the other entries on the list.
Christina Henry is best known for her dark fairy tale retellings. The Mermaid, however, is less grim than her other works and follows Amelia, a mermaid who falls in love with a Maine fisherman and then, when he is taken away from her by the sea, decides to become an attraction in P.T. Barnum’s American Museum in New York City. Amelia is a wonderfully strong character who, as a creature of the ocean, is unburdened by the societal constraints placed on women in the mid-1800s, especially the expectation that she should be quiet and demure in public. She knows who she is, and she knows who she loves, and her story is an engaging yet soothing one that also made my heart ache in the best way.
