Gone Girl by Gillian FlynnRead about another entry on the list.
On the surface, the anniversary treasure hunts that Amy sets for husband Nick are a romantic tradition, a celebration of shared memories. In reality, they’re a series of impossible tests: how well does he know his wife? Nowhere near well enough, as it turns out when Amy goes missing on their fifth anniversary – leaving behind a trail of clues that are carefully plotted to draw Nick into a larger, more sinister plot. In a novel of parallel narratives that double back on themselves, Amy’s clues are similarly slippery, loaded with double meanings; shared jokes become secret weapons in this story of love curdling into hate.
