Okay kiddo, Brides of the Islamic State is a term used to describe women who get married to members of a group called ISIS. These men believe in a really strict version of a religion called Islam, and they want to create their own country based on their beliefs.
So some women from all around the world have decided to go and marry these men, even though it's really dangerous and against the law in most places. They think it's a good thing to do because they believe in what these men are fighting for.
But here's the problem: ISIS is a very violent group that does a lot of bad things. They hurt and kill people who don't agree with them, and they don't treat women very well either. So when these women go to marry these men, they are putting themselves in danger and supporting something that is really hurtful to a lot of people.
It's important to remember that just because someone has a different belief or religion, it doesn't mean they can hurt other people. Everyone deserves to be safe and happy, and going to join a group like ISIS can actually be really dangerous and scary.
