Leonora Potter-childhood not very childish(Fem Harry Potter/crossover)

Prologue

AN : this is my first fan fiction and English isn't my first language, so please be patient with me and help me correct any mistakes.
I appreciate comments and suggestions !!
And I don't own Harry Potter or Percy Jackson or DL or avengers or any fandom that may come along the story line.
Thanks for reading !!

Serafina Di Angelo watched from the shadows as the wedding was taking place while trying to keep an uninterested mask on her expression and failing miserably as a lone tear escaped her tearful eyes as she watched the couple saying their vows and share a kiss.
With one last glance at them she turned around and disappeared with a quiet 'pop'.

Said couple were non other than James Charlus Potter and Lilly Morgana Potter-Evans
Who have just finished their schooling a few months ago and have already joined the order of the Phoenix to fight in the war taking place in Magical Britain.

Lily and James started dating in their 7th year at Hogwarts.

They are in love and wanted to get married regardless of the war going on.

Lily also has a scientific conference to attend in America organized by Stark company.

While most Muggleborns cease their muggle education after getting into Hogwarts, Lily's parents insisted that she has to continue her education and brought her tutors during her summer vacations and she took the tests and got very high marks , lily Evans dream is to find a way for magic and technology to work together thus this conference which she'll attend and stay for a few months to work on some projects with some of the best muggle scientists and then she'll return for Britain to fight the war with her husband and friends.

6 months later...

" That was quit the successful results we've got here lily .wow!! this will be quite profitable!! " Tony said enthusiastic about the new stark tech they just made .

Lily forced a smile and said good bye to her friend for the past few months ,she was worried, the war back in England isn't getting any better and she can't wait to go and fight alongside her friends and husband...

1 month later ...

The battle place was full of many different shades of light , one would think it's a beautiful sight to behold ;however, those lights were in fact spells and some are more deadly than others especially a certain green one.

Lily Potter and Alice Longbottom were fighting side by side each one protecting the back of the other and fighting fiercely to protect each other.

" DIE you filthy MUDBLOOD  " screamed Bellatrix in insanity.

Then in one fast moment Bellatrix Lestrange threw a dark purple spell that neither lily nor Alice were familiar with and it came so fast that lily didn't have time to react and it hit her in the stomach, lily excepted pain or to die slowly or something equally if not more painful and horrible, she closed her eye waiting for the pain but it never came.

" YOU'LL PAY FOR THAT " screamed Alice as she threw a quiet nasty jinx towards Bellatrix only for her to apperate away with the other death Eaters.
"Are you okay lily ? " Alice asked lily with concern in her voice as she helped her to get up so they can apperate to st. Mongos.
" lily what happened? " asked James frantically as he approached them with Sirius and Remus following close behind with worry all over their faces.
"I really don't know " said Lilly which confusion in her voice " I ..I don't feel any pain or anything!!"
" let's go check with poppy just in case "

.........................................

" whatever that spell was I can't detect any damage to your organs... hmm... the heart is fine, the brain, liver, lungs.... they're all ok, though I'd prefer if you visit at any development any change , even if it's nothing but a fever or a slight headache, is that clear ?"
" yes ma'am "

...................................

Little did they know that this spell didn't go wrong but it was there just waiting, waiting for the right moment to play it's part....

.......................
Ok so this was the first chapter what do you think?
And just a few things I want to point to :

1 - Serafina Di Angelo is an oc but will not appear for many coming chapters, any idea who she is ? Why she's crying? Or her link to Nico Di Angelo ? Any guesses?

2 - I wanted to start this story from before Leonora was born because I really wanted to write about James and lily.

3 - yes this will include avengers and stuff but not yet not in this book but I needed to establish the friendship between Lily and Tony Stark for when Leonora and Tony actually meet .

OH and the pic above is how the spell looks from the front but I don't own it I found it on google.
