Eleanor Catton said this quote

She gave a shiver, and suddenly clutched her arms about her body. She spoke, Gascoigne thought, with an exhilarated fatigue, the kind that comes after the first blush of love, when the self has lost its mooring, and, half-drowning, succumbs to a fearful tide. But addiction was not love; it could not be love. Gascoigne could not romanticize the purple shadows underneath her eyes, her wasted limbs, the dreamy disorientation with which she spoke; but even so, he thought, it was uncanny that opium's ruin could mirror love's raptures with such fidelity.
