Marilena Tapaki grew up surrounded by many children's books. She studied Biology, Biomedicine and Genetic Counseling. She currently works as a Genetic Counselor. Her passion for writing and her love for children's books led her to create her first children's book entitled "Where Are You Saying?" in 2024. The book has been approved by the Ministry of Education as supporting educational material for Primary Education and was included in the shortlist for the 2024 State Literature Awards. In 2025, a children's theater performance based on the book of the same name was presented by the Dentro Theater.
