All the monies raised from the book will go to fund both SNOG (Sydney Neurology Oncology Group) which aims to improve the management of brain tumors through targeted research, information and constant scrutiny of treatment options and HEADRUSH, a solely volunteer-run, USA Madison-based, non-profit organization whose mission is to significantly improve the future of Brain Tumor research, treatment, and survivorship.

Other celebs involved in the project include Dianna Agron, Justin Bieber, Miley Cyrus, Ashley Greene, Liam Hemsworth, Daren Kagasoff, Leighton Meester, Brittany Snow, and Shailene Woodley.
