Ms. Marvel is, in my opinion, the best new comic book character in at least the last decade. Her story is unique, inspiring, hilarious, filled with genuine emotion. There is no book I recommend more highly, especially for new readers.
The story of Ms Marvel, Kamala Khan, began in 2014. You should be able to go in fresh, but there is a little backstory I like to tell people: There was an alien hero named Mar-Vell who went by the hero name Captain Marvel. His powers were transferred to an Air-Force Major Carol Danvers, who became a hero under the name Ms. Marvel. Long after Mar-Vell's death, Carol Danvers took up the title Captain Marvel ( Where to start reading Captain Marvel ), leaving her old title Ms. Marvel unused. That is where this story begins.
