The "Adventures of Fren" series is a unique combination of print books and interactive digital stories that was created through a two-year collaboration between designers and medical professionals. This project involved extensive research, development, and multiple rounds of clinical testing and feedback from experts. The result is a seven-book series that offers maximum flexibility to accommodate the needs of child-patients with a wide range of ages and medical conditions. The series was designed with the ability to introduce the content in any order, allowing it to align with the specific journey of each child and help prepare them for medical procedures. With its innovative approach, the "Adventures of Fren" series has become a valuable tool for healthcare professionals and a beloved resource for children facing medical challenges.
