Love me back / Merritt Tierce.

Enhanced descriptions from Syndetics:

From "5 Under 35" honoree and Rona Jaffe Award-winner comes an urgent, intensely visceral debut novel about a young waitress whose downward spiral is narrated in electric prose

Marie, a young single mother, lands a job at an upscale Dallas steakhouse. She is preternaturally attuned to the appetites of her patrons, but quickly learns to hide her private struggle behind an easy smile and a crisp white apron. In a world of long hours and late nights, where everything runs on a currency of favors, cash and cachet, Marie gives in to brutally self-destructive impulses. She loses herself in a tangle of bodies and the kind of coke that 'napalms your emotional synapses.' But obliteration--not pleasure--is her goal. Pulsing with fierce, almost feral energy, Love Me Back is an unapologetic portrait of a woman cutting a precarious path through early adulthood. In the words of Ben Fountain, author of Billy Lynn's Long Halftime Walk , "Tierce roams like an avenging angel across the landscape of twenty-first century American decadence, and the truths she writes achieve a state of near-sacred subversion."
