For fans of The Midnight Library and In Five Years, The Unwritten Rules of Magic is a spellbinding novel that blends magic and memory in an unforgettable journey through love, grief, and the hidden cost of perfection across three generations of women.

Emerson Clarke can’t remember a time when she felt in control of her life. Her father—a celebrated author—blew in and out of her childhood like a hurricane until he got Alzheimer’s. Her mother numbed loneliness with gin. And recently, her teen daughter has shut her out without explanation. The only place Emerson has ever been in charge is in front of the keyboard where, as a ghostwriter, she dictates everything that happens on the page. If only she could arrange reality the same way, life could be perfect. An impossible fantasy—or so she believes until she makes a startling discovery.

After her father’s wake, Emerson steals her father’s vintage typewriter—the very one he’d forbidden anyone to touch—and tests its keys by typing out a frivolous wish. After it comes true the very next day, she tries another. When those words also spring to life, she becomes obsessed with using the typewriter to engineer happiness for herself and her daughter. Easier said than done.

As Emerson shapes her real-life circumstances, she uncovers disturbing truths about her family’s history and the unexpected cost for each story-come-true. She should destroy the typewriter, but when her daughter's secret finally emerges, Emerson is torn between paying the price for bending fate and embracing the uncertainty of an unscripted life.
