Minibio elaborada para um projeto de livros infantis em inglês que escrevi, o texto é da editora, mas gostei demais:"Guilherme Kroll is someone whose love for books is remarkable. As an editor, Guilherme has dedicated his life to not only writing and adapting children’s literature, but also to translating several titles, most of which are related to the geek environment. He is one of the founders of Balão Editorial, a ten-year-old publishing company dedicated to spreading the art of comics."
