Keeley, a simple plain Jane, hits the jackpot. [No, she did not win the lottery!] At least that's what she thinks when she marries the most eligible bachelor in New York City: Aaron, a wealthy cold-hearted heartthrob and Tycoon. She wants to show the world that she deserves her position and bends over backward to fit into his world. One beautiful day, Aaron hands her a document asking her to sign. A divorce paper... "She's pregnant, and I need to take responsibility." That is the last thing that keeps on playing in her mind before she takes her last breath. Keeley dies, a 'hit and run'. [End of story. Not!] For some unexplainable reason, she wakes up as her younger self. A young high school girl, around the time when she first meets her cheating husband. Remembering her life with Aaron before she died, she makes a promise to herself that she will do everything in her power to avoid him at all costs. Will she be able to keep her promise when Aaron has his own plans as well, specifically for her? Or will she repeat history and fall for him once more... Why not journey with me and find out the truth behind their story. *Cover art by polkadottedscrunchie*

I changed various laws so expect some different powers from the mc. I got the cover on pinterest if you own that just message me and I will drop it. Check the tags for more info. Expect tons of grammatical errors and misspellings. It's my first book in english.
