Dave Eggers is an award-winning author whose novels for adults include The Circle, The Monk of Mokha, and Heroes of the Frontier. His books for children include Her Right Foot, The Lifters, This Bridge Will Not Be Gray, and What Can a Citizen Do? He is the co-founder of 826 Valencia, a youth writing and tutoring centre in San Francisco that empowers young people through the written word and which has inspired similar centres all over the world. In 2018, Eggers co-founded The International Congress of Youth Voices, an annual gathering of 100 extraordinary young writers and activists.

Dashingly illustrated... Fresh, idiosyncratic and winning... Dave Eggers takes nicely judged liberties with Jules Verne's Twenty Thousand Leagues Under the Sea as Captain Nemo but stays true to its spirit. There is nonstop entertainment on board his submarine - the writing is such fun
