Sally Jackson is the human mother of Greek demigod Percy Jackson. She is currently married to Paul Blofis.
When she was five years old, her parents Jim and Laura Jackson, both died in a plane crash 150 miles south of Lake Ontario at 3 A.M. No one survived the accident and the cause of the crash is left unknown. She was raised by her uncle Rich Jackson. During Sally's last year of high school, Rich died of cancer, leaving Sally to have to work small jobs, because she had dropped out of high school to take care of him. She met Poseidon twelve years before the series started, noticing his trident as she could see through the Mist. They fell in love and after spending the summer with Poseidon, their child was conceived. Poseidon kept Sally a secret from his brother, Zeus. Poseidon was forced to return to the sea; until their son Percy discovered that he was a demigod, Sally told him that his father was not "dead" but "lost at sea", a possible hint about Percy's dad. Twelve years later she learned that her son was the half-blood of the great prophecy that could be holding the fate of Olympus and the gods in his hands when he reached the age of sixteen.
Sally was married to Gabe Ugliano so that monsters would stay away from her son, in the hope that Gabe's smelly and repulsive human scent would cover Percy's scent. However, Gabe was abusive to Sally when Percy was not around, hitting her and treating her badly. She works in a candy shop called Sweet on America, loves the color blue, and blue food. This is because of a fight she got into with Gabe over whether or not food could be blue. Sally always went out of her way to always eat blue food, occasionally baking blue cakes, and bringing home blue candy from work.
