Can you recommend a novel with a strong protagonist?

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*

A war goddess was reborn and obtained a Mutual Separation agreement. She only wanted to remove her armor, return to the countryside, and marry an honest man. Perhaps she would have three children, and they could live quiet lives farming and weaving. By chance, she joined a refugee group and met a man who was adept in both the pen and the sword. She ventured with the refugee group since spring until winter. The man was very protective of her, and she figured it would be nice to marry him. He had strong arms, so he could surely plow large fields. They could raise their children together and live happy lives. However, who knew that the man was actually a dragon?! Oh well, one must be content with the partner they had chosen, so she shall soar with the dragon! The war goddess donned her armor once more and dominated the battlefield with her man! The emperor’s walls, countless soldiers, and vicious schemes. She feared nothing as long as she stood beside her husband. Just like that, they accidentally charged into the palace with their army. Sigh, she had only wanted to bear three kids and live peacefully. The man pressed her against the wall and asked in a low voice, “You want kids? I’ll satisfy your needs.”

"A Villainess should be strong," she thought as she vaporized an entire lake.

Will she achieve her goals, or will she meet her downfall before that? -Photo not mine, I found it on Pinterest ^^-
