Learning Not to Drown

Not sure if this is the right fit?

Consider 11/22/63 by Stephen King. Recommended by 4 sources.

“Starts as a lean, suspenseful time-travel premise that quickly settles into an immersive, character-focused saga. Its chief useful part is the way everyday 1960s small-town life and personal relationships make the historical stakes feel immediate; the novel rewards readers who relish atmosphere and slow moral puzzles. The main limitation is length and digressions—long domestic passages and episodic subplots stretch the middle and can undercut urgency for readers who wanted a tighter thriller.”
