Illustrator April Hartmann brought the playful story "Mismatched" to life with vibrant, expressive artwork and full design support. In addition to illustrating the book, Hartmann provided title treatments, complete cover design (front, back, and spine), interior layout, and print-ready file preparation. She also consulted on copyright, barcode, and ISBN setup—ensuring a polished, professional finish from concept to publication. Written by Makenzie Waters, "Mismatched" tells the story of Sammy Sock, who discovers that the best matches aren’t always what you expect—just like great collaborations between authors and illustrators.
