Just before Henry Aster's birth, his father -- outsized literary ambition and pregnant wife in tow -- reluctantly returns to the small Appalachian town in which he was raised and installs his young family in an immense house of iron and glass perched high on the side of a mountain. There, Henry grows up under the writing desk of this fiercely brilliant man. But when tragedy tips his father toward a fearsome unraveling, what was once a young son's reverence is poisoned and Henry flees, not to return until years later when he, too, must go home again.
