In the vein of Jesmyn Ward's Salvage the Bones and Sue Monk Kidd's The Secret Life of Bees, a coming-of-age novel told by almost-eleven-year-old Kenyatta Bernice (KB), as she and her sister try to make sense of their new life with their estranged grandfather in the wake of their father's death and their mother's disappearance.
 
An ode to Black girlhood and adolescence as seen through KB's eyes, What the Fireflies Knew follows KB after her father dies of an overdose and the debts incurred from his addiction cause the loss of the family home in Detroit. Soon thereafter, KB and her teenage sister, Nia, are sent by their overwhelmed mother to live with their estranged grandfather in Lansing, Michigan. Over the course of a single sweltering summer, KB attempts to navigate a world that has turned upside down.

Her father has been labeled a fiend. Her mother's smile no longer reaches her eyes. Her sister, once her best friend, now feels like a stranger. Her grandfather is grumpy and silent. The white kids who live across the street are friendly, but only sometimes. And they're all keeping secrets. As KB vacillates between resentment, abandonment, and loneliness, she is forced to carve out a different identity for herself and find her own voice.

A dazzling and moving novel about family, identity, and race, What the Fireflies Knew poignantly reveals that heartbreaking but necessary component of growing up--the realization that loved ones can be flawed and that the perfect family we all dream of looks different up close.
Praise for What the Fireflies Knew

“Combining complex characters, writing that instantly penetrates your heart, and the restorative power of nature, What the Fireflies Knew is a luminous reminder that sometimes the only true path to healing is through facing our painful histories, and that we don’t have to do it alone. With a debut novel this remarkable, Kai Harris is a writer I hope is around for a long, long time.”
—Mateo Askaripour, New York Times bestselling author of Black Buck

"What the Fireflies Knew is a fabulous debut and truly a gem of a novel, full of the beauty, tenderness, and poignancy of Black girlhood.”
—Deesha Philyaw, author of The Secret Lives of Church Ladies

"What the Fireflies Knew is sharp and graceful, poignant in its depiction of a family learning to acknowledge what’s been broken in order to piece itself back together. Kai Harris beautifully captures what it feels like to be out of place—in a city, in a body, in a family, in the turmoil of adolescence— and then just as gracefully reminds us what it can feel like to find your way back to yourself in spite of everything. This book introduces a bold and necessary new writer, generous in her capacity for holding onto hope without erasing trauma."
—Danielle Evans, author of The Office of Historical Corrections and Before You Suffocate Your Own Fool Self


"In this gorgeous and poignant novel, Kai Harris writes a stunningly crafted tale that explores the beauty and hard truths of life, loss, and survival through the lens of an unforgettable narrator. This story of a young black girl navigating the labyrinth of self and family secrets is told in an authentic voice, filled with well observed details and elegant prose. Harris's first novel showcases her gift as a superb storyteller." 
—Nicole Dennis-Benn, bestselling author of Patsy and Here Comes the Sun

“Kai Harris's fierce, lyrical writing drew me in from the first page. KB is an unforgettable narrator whose voice comes vibrantly to life through her journey from childhood to adulthood, even as she grapples with the forces that tear families apart and the power that holds them together. This is an extraordinary, powerful debut, and I hope there will be more to come from Harris.”
Abi Daré, New York Times bestselling author of The Girl with the Louding Voice

"A story of Black girlhood from a promising new voice in fiction."
