Estelle Fontaine is the most trusted woman in beauty. Maison Fontaine has two million devotees, a waiting list for every serum, and, in one month, a buyout offer that will make its founder richer than God. There is only one rule at the top: stay there. So when a rival chemist gets a little too close to Estelle's signature formula, and a true-crime podcaster starts asking aloud why Maison Fontaine's competitors keep meeting such spectacularly bad luck, Estelle does what she has always done. She handles it. Calmly. Beautifully. Permanently. She never set out to become a killer. It simply keeps happening. Results May Vary is a glossy, wickedly funny crime novel narrated by a woman who is perfectly honest with you and lying to everyone else in the room. Killer results. Literally.
