Gaby Dunn and Allison Raskin have pledged to donate their proceeds from their young adult novel I Hate Everyone But You book tour to the United Way Houston.

The YouTube stars are heading out on tour to promote the book, which is being published by Wednesday Books’ inaugural list, an imprint of St. Martin’s Press, and tickets are on sale now.

The tour begins in Philadelphia and the duo was expected in Austin, Texas Sept. 11.

General admission is around $17, and the cost of a VIP meet and greet, signed book, merch is just $80.

The book is written in styled text and email exchanges from two best friends, Ava and Gen, who are away at college across the country from one another. The novel addresses the issues of first love, weird roommates, coming out, OCD and everything in between according to TubeFilter.

The pair left Buzzfeed in 2015 to pursue their passion project Just Between Us and have garnered over 750,000 subscribers and more than 100 MILLION views.
