Unchallenged

Earth was destroied and not many managed to survive. Some said it was a blessing others wishpered it was a curse to still be alive.
It's been a month since The Great Darkness. Ida- a vet - and her two adopted children are trying helplessly to find their lost families. Traped in a demanding world where nobody knows anybody and anything, the young new mother faces challenges she's never imagined before. When she thought nothing else could affect her even more, a strange man knocked at her door: Nikolay - the ex convict.
Will they manage to accept their new faith and get used to one another?

This is my first ever published story. It was my dream to publish it somewhere because I had this plot in my mind for a very long time. I only wish that you could read it and comment what you think about it and what I could improve for this story to be more attractive.
Thank you!
