Jenni L. Walsh is the USA Today bestselling author of twelve books for adults and children, spending her days knee deep in words in Philadelphia’s suburbia. Beyond words, Jenni is a mama (of a soulful ten-year-old, a dinosaur-loving eight-year-old, and six needy furbabies), a wife, a Philly and 'Nova sports fan.

But where did it all begin? Jenni spent her early years dabbling in various forms of writing and with her nose in a book. Her writing chops first began to develop through one-page stories. Never fail, the storyline followed the same progression: girl meets boy, girl marries boy, girl and boy have baby. That's it.

Now Jenni has moved on to stories with a bit more depth and, for the mamas, Side by Side is a historical women's fiction story of America’s most infamous crime spree of Bonnie and Clyde told in the raw and honest voice of the woman who lived it, Bonnie Parker. In Becoming Bonnie, a prequel set in the Roaring Twenties, a picture of Bonnie's earlier life, before and while she meets Clyde, is brought to life. Jenni's third historical women's fiction book A Betting Woman takes us to the California gold rush, featuring a little known woman from history, Eleanor Dumont, but who is largely remembered by the moniker Madame Moustache. In The Call of the Wrens, Jenni introduces readers to the Women's Royal Naval Service (the Wrens), who carried wartime secrets on their shoulders as motorcycle dispatch riders during both world wars. Unsinkable ​is Jenni's first bestselling novel, hitting the USA Today bestsellers list, and is about two resilient women, one of which is the real-life Violet Jessop who survived the Titanic and two additional maritime disasters. Jenni's next historical novel Ace, Marvel, Spy, releasing in January 2025, features Alice Marble, who was the world's number one women's tennis player, an editor for the Wonder Woman comics, and a spy during the Second World War. Jenni is also contracted for an untitled book in 2026.

For the kiddos, Jenni's debut middle grade books, She Dared, features true stories from women who, at a young age, accomplished daring feats of perseverance and bravery. She is also the author of I Am Defiance, inspired by a real-life resistance group, known as the White Rose. Jenni has contributed Hettie and the London Blitz: A World War II Survival Story to the Girl's Survive series. Revolutionary War hero Sybil Ludington, who is often known as the "female Paul Revere," is brought to life in By the Light of Fireflies, Jenni's first historical novel with a touch of magical realism. Over and Out is a thrilling and fast-paced espionage and escape story that is inspired by real stories of life in East Berlin during the Cold War. Operation: Happy, set during the attack on Pearl Harbor, tells the story of a real-life survivor and includes the POV of her dog, Happy, to soften the events of one of America's most notable moments in history. In 2025, Jenni is excited to be releasing her first contemporary novel, a mystery/adventure story called The Bug Bandits, which is inspired by a real heist and the shenanigans of Home Alone.
