Stella di Angelo

Stella di Angelo (nee Jackson) is the wife of Nico di Angelo and mother of Jade and Seth di Angelo. She is a daughter of Poseidon and full-blood sister of Percy Jackson.

History
Stella was born on June 1, 1997 to Sally Jackson and Poseidon. Sally was already married to Gabe at that time, and Sally couldn't afford to raise both Stella and Percy, so with a heavy heart, she left Stella on the doorstep of a house. She was found by Abigail Jameson, her adoptive mother, who was a daughter of Zeus. She was suspected to be a half-blood, and so Abigail gave her a special necklace to hide her scent.

Demigods: Summer
In the first chapter, Stella was introduced, along with her half-siblings, Emily Gagne and Pheonix. She was brought to camp by Fern, a satyr, after being claimed by Poseidon in front of the whole freshman class. As she entered the cabin, she saw Percy eating a bowl of Lucky Charms. As she introduced herself, saying her surname Jackson, Percy spit out the cereal. Then, she meets Pheonix and Emily, and Emily decides to show her around camp. Near the Amphiteatre, they bump into Nico, who is Emily's crush. It seems as though she has this whole 'crush-at-first-sight' thing because she thinks that, "He is kind of cute… But no. No, Emily likes him. And if I've learned anything, girls do not date their friend's crushes. And I resolve to stay as far away from him. But I promised to see him later! God, this is so confusing!"

In the second chapter, it doesn't shine much on the Poseidon cabin, but there are a few mentions. This chapter was focused on Derrick, son of Hera. It has pretty much hinted that Nico likes Stella, because a line says, "when I stopped to say hello to Nyx at the Hades Table, Allie gave Nico a flirty wink and a wave. He was distracted and only nodded in her general direction. He was too interested in watching the new girl to notice my sister."

In the filler chapter, Nico teaches Stella to ride a Pegasus. She described it to be "the best experience I've had in my entire life, besides being with Nico." In the end, Nico kisses her and they officially become a couple.

In the other filler chapter, the NAFC or the Nico di Angelo Fan Club, discovers their relationship and tries everything they can to break them up, but to no avail.

In the Karaoke chapter, she sings 'Say it Again' by Marie Digby, which was dedicated to Nico. She is described to be a good singer, as one of the last few lines says, "With her amazing soprano voice, she got a standing ovation." Nico even climed up on stage and kissed her on the cheek.
