Edition details
Book Summary
A family builds a giant raft to journey down the Amazon River, but their voyage is shadowed by a dark secret: the father, Joam Garral, is actually Joam Dacosta, a man wrongly condemned for a crime. As they travel, a blackmailer threatens to expose his past, leading to a race against time to prove his innocence.
The novel follows the Garral family as they construct a massive raft, the jangada, to descend the Amazon River from Iquitos to Belém. The patriarch, Joam Garral, is secretly Joam Dacosta, a man who fled Brazil twenty-three years ago after being falsely accused of a diamond theft and murder. Torres, a former slave hunter, discovers a cryptogram that can prove Joam's innocence and attempts to extort money from him. When Torres is killed, the cryptogram is recovered but proves indecipherable. As Joam is arrested and sentenced to death, his family and friends—especially his son Benito, his future son-in-law Manoel, and the barber Fragoso—work desperately to crack the code. Fragoso learns the name of Torres's deceased accomplice, Ortega, which allows Judge Jarriquez to decipher the cryptogram, revealing Ortega as the true criminal. Joam is exonerated, and the journey concludes with the double wedding of Manoel and Minha, and Fragoso and Lina, celebrating justice and family unity.

Narrative arc
Story tension across the book.
Torres
Torres joins the jangada as a fellow traveler rescued in the forest, but his quiet reserve and pointed questions about the Garrals mark him as something other than a grateful passenger. He fixates on Minha and on Joam Garral's past, hinting at knowledge he refuses to name, and his shifting eyes betray a man pursuing a private advantage. His presence turns a leisurely river voyage into a slow-burning contest of watchfulness.
Benito Garral
Benito is the energetic young Garral who manages the commercial side of the jangada voyage and takes charge when action is needed. He is quick to trust and quicker to act, whether hunting game along the banks or confronting the unease Torres stirs in the family. His loyalty to his father and sister makes him the story's forward-driving force, forever pushing toward the truth behind the mystery.
Joam Garral
Joam Garral is the patriarch of a thriving plantation at Iquitos, a man whose competence and generosity have made him beloved by family, servants, and neighbors alike. Yet his calm authority masks a buried identity, and the arrival of Torres threatens to expose what he has spent years protecting. His quiet struggle between duty to his family and the demands of his hidden past anchors the novel's central tension.
Manoel Valdez
Manoel is the steady, observant counterweight to Benito's impulsiveness, a doctor engaged to Minha Garral and welcomed into the family as a son. From the moment Torres appears, Manoel distrusts him, noting the man's shifting eyes and calculating manner while the others extend hospitality. His loyalty and clear sight make him the family's quiet guardian as the voyage downriver grows increasingly perilous.
Joam Dacosta
Joam Dacosta is the identity Joam Garral left behind after being wrongly condemned in a notorious affair of stolen diamonds. A dying accomplice entrusted proofs of his innocence to Torres, who now uses them as a weapon of extortion, demanding Minha's hand in exchange for silence. The shadow of Dacosta turns a family river journey into a desperate race against exposure and execution.
Fragoso
Fragoso is a good-natured jack-of-all-trades whose sociability and quick hands make him welcome wherever he goes along the Amazon. It is his casual generosity — offering Torres a free shave and speaking up for him — that brings the dangerous stranger into the Garrals' company. Lighthearted yet genuinely helpful, he becomes an unlikely but valued ally to the family as the voyage unfolds.
Justice and Innocence
The central mystery revolves around Joam Garral (Joam Dacosta), who was wrongly condemned for a crime and lives under a false identity; the narrative explores the quest to prove his innocence and the eventual reparation of justice.
Family and Loyalty
The Garral family's unity and mutual support are emphasized throughout, especially as they face danger and uncertainty; characters like Benito, Manoel, and Yaquita demonstrate unwavering loyalty to Joam.
Nature and the Amazon River
The Amazon River and its surrounding forests are depicted as both majestic and perilous, serving as the setting for the journey and symbolizing the vast, untamed power of nature that shapes the characters' lives.
Deception and Truth
Themes of hidden identities, secrets, and extortion drive the plot, as Torres attempts to exploit Joam's past, and the characters grapple with revealing or concealing the truth.
