Scholastic has stuck a deal with YouTube star Jenn McAllister (known as JennXPenn to the Internet) for “Really Professional Internet Person,” the publisher announced Friday.

McAllister’s tome will include advice for creating Web content as well as her thoughts on navigating cyber-fame.

“Jenn has an incredible voice for teens, inspiring them to be authentic while encouraging them to not take everything so seriously,” said Scholastic VP and publisher Debra Dorfman in a statement. “Everyone knows Jenn is passionate about her videos, and that same dedication is evident in her new book. We are Jenn ‘followers’ and are so glad she is now part of the Scholastic family.”

Eighteen-year-old McAllister will also share the story of her transformation from shy preteen to YouTube personality. The YouTuber has collaborated with brands including Brandy Melville, Old Navy and Mattel. She also appeared in the feature film “Bad Night” with Casey Wilson and Adam Pally.

McAllister’s YouTube videos feature the teen doling out advice on topics like online gaming, flirtation through the use of One Direction lyrics and hotel-room boredom.

“Being able to work with a publisher like Scholastic isn’t something everyone stumbles upon in their lifetime, so to have this incredible opportunity to share the things I don’t necessarily open up about in my day-to-day life was liberating,” McAllister said in a statement. “I’m excited for my fans to get an inside look at my journey mixed in with my humor, and to continue to grow with me through the book both mentally and emotionally.”

“Really Professional Internet Person” will be published in paperback and e-book formats in September.

McAllister is repped by UTA and managed by Big Frame.
