Prisoners (co-authored with Branca Fabrício). São Paulo: Ática, 1994.
This book is part of a 12-volume series of readers (Buddies) for secondary schools in Brazil. The stories revolve around the adventures of a group of friends from childhood into their teenage years, and they deal with relevant issues for that age group such as friendship, concerns about the future, changes in their bodies, leisure and relationships. In Prisoners, seven children and their dog are made prisoners in a cave by an ambitious and unscrupulous scientist whose experiments are polluting a local river. The kids manage to escape eventually, but they have a larger task: to terminate the experiments and bring the scientist to justice.
