In Blood Water Paint, Artemisia Gentileschi is a fantastic painter. She is the "apprentice" of her father. But in reality, she just paints for him to take credit of her work, not unlike many famous artists in her time period.
Artemisia was constantly working for her father, taking his every order. Her mother had passed away many years ago, leaving it to only be her, her father, and useless brothers.
Artemisia meets a man named Tino. Tino was hired by Artemisia's father to teach her more about painting. Artemisia quickly finds herself falling for Tino.
Tino invites Artemisia to his studio to paint, rather than the dungeon-like place she was before.
Throughout the course of the story, we see a different perspective of a girl named Susanna, who is closely relate to her mother. Artemisia would keep the stories of Susanna in her paintings often. Her mother would always tell her about Susanna's story.
Susanna's story later becomes very important to Artemisia's relationships and bravery. The story also represents resilience, which her mother taught her through this story.
Later in this story, we find out that Tino was a scoundrel who did not have the same intentions that Artemisia did. He used her in terrible ways and left.
