HELP!!! What can I add or change to this plot so it won’t be cliche or a recycled plot???

Okay my story is a urban fantasy/sci fi type story with romance action, comedy, and a little mystery.

Main Characters: Zaria, Lex (short for Alexavier)

Plot: (bare with me because I’m extremely terrible at explaining things and summarizing stuff) Zaria has never had anybody. She grew up in a children’s home in Atlanata and was one of the ones who never gets adopted. She’s 18 now and on her own. Her life isn’t going to well because she lives in the projects and has to work as a maid in a hotel. But all that’s the backstory and not super important. So she decides try to figure out who she is. She’s not interested in starting a relationship with her parents, she just wants to know who she is so she can have some sort of identity. She goes back to the Home and starts doing research. She gets a name of this city called Unknown ( I haven’t come up with a cool original name yet so if you have suggestions that would be nice.) and she decides to search for it. Some creepy old dude (haven’t figured out how they meet) tells her it is located behing the rock wall at Stone Moutain park and she isn’t sure if he’s forreal or drunk but she decides to search anyway. She goes through the wall and Badaboom! She’s in Unknown. She thinks she dreaming because the place is weird and different. (anyways i’m going to try to shorten this by just leaving out details and putting in the major points)
-She finds out she’s a witch and this where I have trouble because I don’t want people to think it’s Harry Potter wannabe or lookalike. Also it’s not just a story with witches/wizards because it will also include or things like werewolves, vampires (not Twiight) and other magical things.
-She moves there and starts college. I also have trouble with this because with the HP plot I don’t want readers to assume it’s like Hogwarts because it will be wayyyyyyy different.
-Makes friends and etc and other stuff you do when you go to college. Gets part time job.
-Falls in love with Lex although she couldn’t stand him at first and they go through a bunch of drama in their relationship.
-Finds out she’s actually the lost princess of city/counrty Unknown who was lost after palace was attacked by Mafia thingy (no name yet)
-Finds out mafia thingy wants to kill her for the pendant she has that has the power to bring back the dead (or something cool and interesting like that but I can’t come up with anything. i’m not really a gothic scifi type so the whole dead thing isn’t my thing so if you have any ideas that would help too.) They want the pendant to take over the country and/or world. They can’t use it because it will only work for the one who rightfully possesses it and the only way they can posses it is if A) she gives it to them or b) they kill her. That’s why they attacked the palace and killed her parents but her dad gave the pendant to her before they captured him.
-Anyways a bunch of other college drama things and the mafia begin to come after her.
-In the end, she mangages to defeat one important member of the mafia which leaves off for sequels and her life is good. (not the mushy gushy happy ending though.)
It’s cool about being honest. I’m trying to better myself as a writer and that means you have to take criticism. That’s why I asked this question because I know some parts are cliched but I need new ideas. It’s kind of hard because pretty much every story idea is cliched or recycled because it’s been done already. Anyways thanks for your help.

Not to sound like I am trash-talking you, and I know I won’t get the best answer because of what I am about to write, but I feel that I have to be honest. It seems like you just jumbled a bunch of plots from different stories together (City of Ember, Harry Potter, etc.) You also seemed to take a lot of cliched ideas (parents are murdered but give her something valuable right before they die, falling in love with the guy you hate, growing up in an orphanage and never getting adopted, lost princess, being hunted down for something given to her that she never thought much of, etc.) Also, the way she discovers the city is kind of weird. Also, you kind of flip flop between real life and magical/sci-fi things. I mean, the mafia hunting down a lost witch princess who lived in the projects, but now lives in a town hidden in a state park? That is kind of confusing.

I know this is harsh, but my advice is to go back to the drawing board. Maybe you could re-use a couple of ideas, but really you need something fresh.

I know people will try to suck up to you and say, "Ohmigod, that sounds soooo good. I so want to read it!", but I feel that I have to be honest. I only say that kind of stuff when something sounds original and exciting, and your story idea just isn’t doing that for me. I really am sorry, but that is just my opinion.

Hope I helped!
