Let me recommend a book to you that fits your requirements. "The Age of the Queen" was a fantasy romance novel written around 2012. The plot was very interesting. After the black tide swept through the world, a new profession was born among intelligent species--resource and energy explorers. The female protagonist was reborn as a baby in this world, from a grass and wood commoner to the title "Queen", living a new and exciting second life! I hope you like this fairy's recommendation.
