Written by Marcia Kupstas, one of Brazil’s most prolific and respected authors for young readers, with more than 170 published books, Frontier combines adventure, self-discovery, archaeology, and environmental awareness in a compelling coming-of-age narrative. Winner of the Mercedes-Benz Revelation Prize for Youth Literature and recipient of other major literary distinctions, Kupstas creates a relatable protagonist whose personal journey unfolds alongside a fascinating exploration of South American history and culture.

A distinctive feature of the novel is its integration of real archaeological discoveries from the Amazon, particularly the geoglyphs found in Acre, which continue to challenge assumptions about the region’s ancient civilizations. The book’s graphic design draws inspiration from these enigmatic geometric earthworks and from Andean visual traditions, reinforcing the atmosphere of exploration and discovery. Through Maurícia’s emotional and physical journey across borders, landscapes, and cultures, Frontier offers an engaging reflection on courage, identity, and the boundaries we overcome within ourselves.
