Princess X Books in Order

Princess X is built around a simple, powerful question: what if the story you made with your best friend started sending you messages years after she died? Cherie Priest's I Am Princess X combines a teen mystery with comic-book pages, using both forms to tell one story about friendship, creativity, grief, and the stubborn hope that someone might still be out there.

May and Libby created Princess X together as kids.

Libby drew the pictures. May wrote the adventures. Their heroine was a sword-carrying princess who could fight monsters, ghosts, and anybody who got in her way. Then Libby and her mother were believed to have died in a car crash, and Princess X disappeared from May's life along with her best friend.

Years later, May is back in Seattle when she spots a Princess X sticker. Soon she finds more signs, including an online comic that feels far too familiar to be a coincidence. The art, the voice, and the details suggest that Libby may not be dead after all. With help from a tech-savvy ally, May follows the clues through the city and into an increasingly dangerous mystery.

The comic is not just decoration.

The Princess X pages give readers a second version of the story, one where a fictional warrior is fighting through dangers that may reflect what is happening in the real world. The format lets the book move quickly between May's investigation and the comic's bold, stylized action. It also captures why shared stories can become their own private language between friends.

This is a standalone story, so I Am Princess X is the only place to begin. It is a good fit for readers who like puzzles, online clues, comics, determined teen protagonists, and mysteries that take friendship seriously. The danger is real, but so is the sense that imagination can give someone a way to ask for help.

It is a mystery with a pink-haired princess and a sharp edge.
