​What’s your favourite novel opener, and why? (Literary sci-fi)

I’m writing a speculative sci-fi about the social ramifications of trauma-erasing technology and the formation of a support group turned hactivist community. The spinal core of the novel however is a mother-son relationship, the son being the central protagonist.

Even though trauma and pain are integral themes, I want there to be a Vonnegut-esque absurdity to it all (I’m ADHD as fuck and a bit loopy) so, despite the darkness, there’s going to be a lot of humour too. Anyhow, let me know which one reels you in, and why. I’m struggling in terms of a starting point but do want to write chronologically.

Thanks for your time!

Option 1:

Arlo lay on the slanted bench calculating whether the ashes of his father contained enough phosphorus to make a grenade. Not enough. The realisation pressed down on him—exacting, desolate—as his grip tightened on the small bear in his arms. Ice crusted his moustache hairs. His blood, thick with cold, circled slow. The hour no longer mattered. Some things time will erase, others carve themselves into the marrow. And stay.

Option 2:

So there Arlo was, pacing the garage and snarling at his father, who lingered, reticent as death in a Tupperware box atop the washing machine. Stage-like against the ripening dusk, a beam of moonlight pooled across the plastic and the sachet of dandelion seeds resting beside it, gathering dust. The more invasive of the two, a subject Arlo was busy fleshing out as he paced up and down, up and down the garage, fire in his belly, arms raised in the default posture. Outside, a car’s tyre drag tore through the night.

Option 3:

Before their twinned unraveling—resentment building as it does, Tower of Babel to an infinite sky—Arlo recalled no more a perfect day than when his mother sat him down in Hope Valley to teach him about the dandelions. What a peculiar thing, hindsight.
