The House in the Cerulean Sea, Part 3: Conflict on the Mainland

In this episode of Books Between Friends, we explore chapters 11–15 of The House in the Cerulean Sea by TJ Klune—where the magic of Marsyas Island truly begins to deepen. Linus continues warming to the children (and vice versa), but his caseworker instincts clash with the growing sense that there’s more to this orphanage—and to Arthur Parnassus—than the files ever revealed.

We break down the tender, funny, and unexpectedly emotional moments that shape these chapters, discuss character growth, and uncover the early sparks of the story’s larger mystery. From heartfelt conversations to small acts of courage, this section of the book reminds us why cozy fantasy hits so hard.
