The Devil's Three Stones 1 - Triangle Jota 17

The story unfolds in the city of Porto during the month of June and marks the reunion of Joana with Gil, the boy she fell in love with in the previous book, "Guardado no Coração" (Kept in the Heart).
Together, the heroes of the Jota Triangle embark on a new adventure when three fire stones of mysterious origin — considered by some to be from the future and by others from hell — fall from the sky. The plot intensifies when the characters discover the tomb of the "squatting man," which contains the enigmatic inscription: "I came from a distant planet and lived among you".
