"Youth Activism, Engagement and Participation, Good Practices & Essential Strategies for Impact" by Amnesty International includes more than 60 case studies focusing on events, music activities, advertising to youth, websites, setting up youth advisory councils, and much more. While it was specifically written for Amnesty national offices, many organisations interested in better engaging youth will probably find it useful!
