Status Updates From The Marsh King's Daughter

From a technical perspective, there is a totally valid attempt here to tell the backstory of growing up with the dad, counter-pointed against the present-day chase through the woods after the dad.
From an emotional perspective, the whole thing just comes across as "thin." so so thin. I realized this is a "thriller" , not literature, but wow it's thin.

Reading this because I wanted to see how modern/popular writers handle outdoor adventure story-telling.
