The manner in which the novel was created is interesting. Readers must ponder over the fact that the book, in true cavalier style, was penned in a swimming pool. De Graf swims a mile a day, and it was during these long aquatic conquests that he was given to stretch his mind and formulate the plot for the novel. Reflective of the manner in which the seeds to the story were sown, the plot is stormy and combines true adventure with boundless passion. De Graf quips that although the novel was penned in a swimming pool, he allowed for enough time for the ink to dry.
Cavalier's Call focuses on the early life of Joao de Aviz, father to Henry the Navigator. The novel describes his appointment in the Court of King Ferdinand I as a young courtier, his brilliant defense of a man accused of murderer, and how he tackles the prosecution led by the powerful Don Antonio Esteves. The romance between Ines Peres Esteves and Joao add pepper to this historical story. Ultimately, Joao de Aviz must lead
in its battle for independence. In a thrilling conclusion that provides a twist, an army of five thousand troops march against de Aviz' struggle and threaten to topple his small, but brave force. Portugal

New World, augur well for the sequel that the author is in the midst of completing. Cavalier's Call provides readers with an opportunity to penetrate the lifestyle and adventure of the period, in a superlative account that makes this novel a compelling masterpiece.
