It is what it sounds like: someone (usually an orphan, but not always) gathers a group of friends and creates their own family.

We can break it down into two parts: New Adult and Fantasy. New Adult refers to the age of the main character. Usually, they are between 18 and 25 years old (though some will argue the starting point should be closer to 21). The fantasy genre is defined by magic; it doesn't have a basis in science or fact. The book might have different species — such as elves, dwarves, and unicorns — or include the use of magic. The setting may or may not be on Earth or on a different planet altogether.
