Kirsty has spent over 12 months out of the past two and a half years as a volunteer. During that time she's done disaster relief work in Bangladesh, Indonesia and twice in Haiti. She has written an ebook called The Underground Guide to International Volunteering (http://www.nerdynomad.com/volunteering) which gives tips and advice to travellers who want to make their trips more meaningful through volunteering. It costs $14 with $7 of each sale being donated to Hands On Disaster Response (http://www.hodr.org), the organization she has spent so much time volunteering with.
