Praise for The Butterfly Effect

“A warm, winning debut from a talented new Midwestern voice.” –J. Ryan Stradal, New York Times bestselling author of Kitchens of the Great Midwest

“Delightfully off-kilter…[Lovably-flawed] Greta’s comically critical point of view interrogates Midwestern norms and gendered stereotypes in a story that explores the legacy of familial dysfunction. Come for the butterflies, and stay for Mans McKenny’s acerbic authorial eye which examines the complexities of the Midwest and its quiet dramas.”
—Rachel Yoder, award-winning author of Nightbitch

“A lovably grumpy and unfiltered heroine. As a reader, you’ll undergo your own metamorphosis and realize how much you needed this story.”
—Faith Salie, Emmy-winning contributor to CBS News Sunday Morning and author of Approval Junkie

“Satisfying, engrossing, interesting.” – KJ Dell’Antonia, author of The Chicken Sisters

“A page-turner.” -Charity Nebbe, Iowa Public Radio
