Sandcastle really digs into a surprisingly large cast, which is one reason the book lingers in your memory. The core is definitely the family on vacation—the mom, dad, and their two daughters—but the book’s strength is how it fleshes out everyone else on that beach too. It’s not just a backdrop; the old couple bickering, the young lovers trying to have a private moment, the local kids causing mischief… they all get these little moments that feel so specific. Even the beach vendor and the lifeguard are sketched in with this dry wit that makes them feel real, not just extras.
And of course, there’s that old man, Mr. Pius, who seems to be the quiet center of the whole thing. He doesn’t say much, but his presence connects all these disparate lives. The graphic novel format lets you read all this on their faces and in their body language in a way prose couldn’t. It’s less about individual bios and more about the collective anxiety and weirdness that unfolds.
