Robtel is the author of Gbagba, an anti-corruption children’s book published by One Moore Book to critical acclaim in 2013 and subsequently placed on the list of supplemental readers for 3rd to 5th graders in Liberia and for Primary 3 in Ghana. In 2014, she applied for and secured a grant from the Open Society Initiative for West Africa (OSIWA) to pilot Gbagba in 10 schools across Montserrado County, Liberia, as well as commissioned a song and video adaptation of the book entitled ‘Gbagba Is Corruption.’ In 2016, Robtel applied for and secured a second grant from OSIWA to pilot Gbagba in Grand Bassa County, Liberia, and convert the book into a radio drama--which aired on 64 commercial and community radio stations across Liberia--and stage play--which debuted with an all-child cast at Monrovia City Hall on September 28, 2017.
Robtel has conducted Gbagba workshops for children in Liberia, Mozambique, Côte d’Ivoire, Jamaica and the UK. With its broad appeal as a Pan-African and universal children’s narrative about ethics, integrity and accountability, Gbagba is currently under review by ministries of education/education boards in Rwanda, Burkina Faso, Niger and Cameroon. A sequel of the book, Jaadeh!, is forthcoming in 2018 and has already been adapted into a song and music video entitled 'Jaadeh Is Integrity'.
