Estelle Maria Stark carries the weight of her father's legacy with a mix of pride and uncertainty. Raised in the shadow of Tony Starks towering achievements, Este is a prodigy in her own right, inheriting her father's genius intellect and his unyielding drive to protect the world. 

She has a heart that beats with a fierce determination to protect those she loves and her compassion and courage inspire the people who enter her life. 

She is the sole reason for Iron Man's existence, and she is the heart of the Avengers themselves.
As she grows up among superheroes and supervillains, she has no idea that she isn't just a genius who can play at being a hero, she is one herself, and every test that she must battle through reveals that she has powers of her own.

In a tale of legacy, self-discovery, and true heroism, enter the world of Estelle Stark and follow her through her journey as Iron Man's daughter.

Being the only child of Tony Stark, Freya was kept out of the spotlight so that she might live a semi-normal life. Unfortunately, how she became Tony Stark's daughter is the main reason why she will never have anything near a semi-normal life. Having been sent to Earth at age seven for her own safety by an unknown source, she has no memory of her life before she landed on Midgard. Tony, accompanied by Happy, happened to be the one who found her and immediately felt like it was his responsibility to take care of her. So, he adopts her and loves her like she's his own flesh and blood. Tony watches her grow into a strong, beautiful, fierce woman, whose intelligence might even surpass his own. If magically appearing in a beam of light from space wasn't crazy enough, Freya eventually began to develop abilities as she got older. The physical manifestation of specific abilities ended up being silver in color. Resulting in Tony giving her the nickname "Mercury." Which was quickly shortened to "Merky." Tony always hoped she would lead a normal life after reaching adulthood. From his perspective, she was. Instead, she was actually recruited into S.H.I.E.L.D. not long after her sixteenth birthday by Nick Fury. Who had been watching her from a distance for nine long years. She's transformed into a ruthless assassin and becomes a force to be reckoned with. Unbreakable bonds with two fellow teammates are also forged in the process. But, what will happen when a series of unimaginable events reveals her origin and gruesome past? Who will she trust? Who will trust her? ~~~~~~~~~~~~~~~~~~~~~~~ Steve Rogers x OC (Stark) (The Avengers - CATWS) **Book one in the Mercury Series** ~~~~~~~~~~~~~~~~~~~~~~~ I DO NOT OWN ANYTHING MARVEL OR DISNEY RELATED!! I only own my original character, Freya Stark/Mercury. Some bits of the story might be changed, but I will stay as true to the movies as I can. Rated mature for language and violence. ~~~~~~~~~~~~~~~~~~~~~~~~
