If you are looking for a book series with a very strong female lead, The Queen of the Tearling by Erika Johansen is the one for you. The story is set i a post-nuclear war world. Throughout the story, we follow the development of Kelsea, a timid yet strong-headed princess hidden away in the woods to be protected from her uncle, the regent of the Tearling. As she comes of age, she is escorted back to the palace where her personality continues to develop as she faces imminent war with the Red Queen. Meanwhile, we also follow the story of how the Tearling was founded.
It is interesting to know that a movie based on this trilogy is coming out soon (no date set yet) with Emma Watson as Kelsea. Honestly, I can’t imagine a better fit.
All in all, I would definitely recommend The Queen of the Tearling for all fiction/fantasy fans. It is very well written and developed. However, you will have to be patient with it in the beginning as it might seem a bit confusing. But, I promise you that it will make more sense as you go along. However, the ending of the trilogy, though victorious, is both unexpected and bittersweet. Regardless, Erika Johansen is a great author nonetheless.
