I lost patience. I thought I was reading a story about "when the giants" came but it may be a lgbtqia story. You have to make choices, like a choose your own adventure. Early on they ask you to pick a gf/bf/partner etc... but they don't let you choose your gender as far as I can tell but they give "you" a penis so ...

idk may come back to it.

on twitter, the author says: I have a new interactive piece about gender and intimacy during a quiet giant apocalypse in the Strange Lusts/Strange Loves issue over at strangehorizons.com
