đ Quick Summary
Told through the eyes of 10-year-old Kenyatta Bernice (KB), What the Fireflies Knew is a tender and deeply emotional coming-of-age story about loss, discovery, and Black girlhood. After her fatherâs death and her motherâs emotional withdrawal, KB and her older sister are sent to live with their estranged grandfather in Lansing, Michigan. There, KB begins to confront everything she doesnât yet understand: grief, womanhood, family secrets, and the complexities of growing up.
Kai Harris crafts KBâs voice with raw honesty and innocenceâmaking you feel every heartbreak and small triumph alongside her. The novel is both lyrical and accessible, capturing the confusion of adolescence and the unspoken traumas that shape us.

đ My Review
This book took a while to get through the plot, however, the writing is soft and poetic, but the emotions run deep. KB is curious, aching, and filled with moments of clarity that only come when you're standing on the edge of growing up too soon.
Harris captures the subtle heartbreaks of being a young Black girl in a world that expects you to be strong before youâre ready. I appreciated how the novel let KB just beâto ask questions, make mistakes, and hold space for her own wonder.
I gave this one 4 out of 5 stars. Itâs a beautiful book that lingers, even if it doesnât rush to resolve everything. Itâs about becomingânot necessarily arrivingâand that alone makes it worth the read.
đš My Scrapbook Spread
The color palette for this spread was inspired by dusk: soft purples, deep golds, and firefly glows. I layered the page with the two sisters deep in thought as they were both going thought their own struggles. The field of flowers represent the field KB would play in along with the image of Charlotte and Bobby. A jar of fireflies sits on the pageâsymbolizing both wonder and containment, just like the story itself.
