here's some background on charlotte doyle - - -
The story starts in the early summer of 1832, as thirteen-year-old Charlotte Doyle prepares to take a voyage from Liverpool, England, to her family's new home in Providence, Rhode Island. Her upper class upbringing and her education give her a very sheltered and narrow view of life. Charlotte finds herself the only passenger and the only female on the ship, the Seahawk. Repeatedly, people tell her she should not be on the ship, but her escort, Mr. Grummage, insists Charlotte go.
On her first day aboard, a black sailor named Zachariah gives her a dirk for protection. He also warns Charlotte about Captain Jaggery, which Charlotte does not believe. The captain and Charlotte become very close and he says that if she ever sees anything suspicious, she must tell him.
After spotting a round-robin, a sign of mutiny, Charlotte warns Jaggery, who heads off the rebellion and kills its ringleader. Charlotte is distressed when Captain Jaggery and 1st mate Mr. Hollybrass whip Zachariah for 50 lashes. Charlotte tries to protect Zachariah by grabbing the whip, but accidentally hits the captain's face. Jaggery is enraged and whips Zachariah mercilessly, leading to his death and funeral.
After the captain has withdrawn his protection of Charlotte, she feels compelled to replace Zachariah as a crew member out of guilt. The crew allows her to join them after she successfully climbs up and down the tallest mast. Upon learning of Charlotte's plans, Captain Jaggery strikes Charlotte across the face, and she vows to reveal his cruelty to the courts after they complete their voyage.
As the Seahawk enters a powerful hurricane, Charlotte falls from the ratlines and is saved by a man whom she believes is Zachariah, despite his apparent death. After the storm, the crew finds First Mate Hollybrass, stabbed in the back by the dirk Zachariah gave Charlotte. She is ordered to the brig, where she finds Zachariah, who has been hiding there since he was thrashed nearly to death. Captain Jaggery holds a trial and finds her guilty of Mr. Hollybrass' murder. As Charlotte has vowed to expose his cruelty when they land, he threatens to hang her unless she will align herself with him and become a respectable young woman again.
With Zachariah's help, Charlotte escapes the prison and plans to steal the captain's guns and usurp his title. Upon her finding Jaggery, he reveals that he killed Hollybrass. He presents her with three choices, all of which she refuses, and flees Jaggery. The Captain attempts to kill her in front of the crew, but falls off the ship to his death. Zachariah leads the crew in naming Charlotte as captain, but she serves primarily as a figurehead for Zachariah due to her lack of experience. They land in Providence, Rhode Island, 12 hours later.
When the Seahawk arrives in Rhode Island, Charlotte returns to her old "proper" behavior and dress. She intends to hide what happened from her family, but her father reads her journal of the voyage. He is appalled, burns the diary, and tells Charlotte that she will be punished and reformed. Charlotte finally decides to escape from her home one night, and returns to the Seahawk to be a sailor with Zachariah and the crew.
