Themes of missing family members and the pain of choosing between two worlds.
The book deals with identity and the feeling of being an outsider in a metaphorical sense through the Mer/Human divide. It also touches on the lingering grief of a missing father. The approach is secular and atmospheric, with a resolution that is hopeful but acknowledges that belonging is a constant choice.
A 10-year-old who feels like they don't quite fit into their social circle or family dynamic and finds solace in nature or the idea of secret worlds. It is for the child who prefers poetic, descriptive prose over fast-paced slapstick.
The scenes involving the Kraken are quite intense and may be scary for sensitive readers. Preview the descriptions of the Deep to ensure your child is comfortable with themes of darkness and isolation. A parent might notice their child becoming withdrawn or expressing that they feel like they are living in two different worlds (common in children of divorce or immigrant families).
Younger readers will focus on the magic of breathing underwater and the thrill of the monster hunt. Older readers will resonate with Sapphire's existential crisis about which world she truly belongs to.
Unlike many mermaid fantasies that are sparkly or light, Dunmore's world is salt-crusted, dangerous, and deeply literary. It treats the ocean as a powerful, wild force rather than a backdrop.
As the second book in the Ingo chronicles, The Deep follows Sapphire and Conor as they are pulled back into the underwater world of the Mer. A legendary monster, the Kraken, has stirred from its slumber, threatening to destroy the undersea civilization. Sapphire, Faro, and Conor must journey into the lightless depths of the ocean to lull the beast back to sleep. The plot focuses on the physical journey into the unknown and the internal struggle Sapphire faces as she feels her human side slipping away.
