The house in the Cerulean Sea (2025) Parents Guide: Is the book OK for kids?

The romance between Linus Baker and Arthur Parnassus is a gentle, slow-burn emotional connection that builds throughout their time on Marsyas Island.

The presence of alcohol serves primarily as a social lubricant for the two adult protagonists to bond and relax after their responsibilities at the orphanage. Tea is the most frequently consumed beverage…
