It's January 1st, 2015, and the UK is the first nation to introduce carbon dioxide rationing, in a drastic bid to combat climate change. As her family spirals out of control, Laura Brown chronicles the first year of rationing with scathing abandon. Will her mother become one with her inner wolf? Will her sister give up her weekends in Ibiza? Does her father love the pig more than her? Can her band the dirty angels make it big? And will Ravi Datta ever notice her? In these dark days, Laura deals with the issues that really matter: love, floods and pigs. The Carbon Diaries 2015 is one girl's drastic bid to stay sane in a world unravelling at the seams.

It's over a year since her last diary and Laura Brown is now in her first year of university in London, a city still struggling to pull itself together in the new rationing era. Laura's right in the heart of it; her band, the dirty angels, are gigging all over town until a police crackdown on rioting students forces them out of the city. After a brief exile on her parents' farm, the angels set off in a battered VW bus on a tour of Europe with the fabulous Tiny Chainsaws in the Distance.

The tour soon unravels, however, in an increasingly dramatic sequence of events that include drought in Europe and Africa, a tidal-wave of desperate immigrants, a water war in the Middle East and a city-wide face off with the army in London. Not to mention infidelity, betrayal, friendship, love and massive courage.

How long can Laura distance herself from the struggle? And more importantly, how can she keep her style and hope alive in a world on the edge of madness?
