I confess I have a soft spot for Cory Doctorow's writing. This book is a brilliant novel, which portrays a plausible future. Walkaways are a different approach to society, based on collaboration, self organisation and freedom. They leave our society, referred to as "default" and live on the fringes of it. They make good use of what we consider waste, they adapt, implement and simply walk away, sort of like nomads, when things get dangerous or when they simply need to.
There's a lot of interesting concepts that are intertwined in this novel, anarchism, 3d printing, resilient networking, immortality through technology, social inequality, pacifism, LGBTQ love, just to name a few.
I will return to it in the future, and will be reccomending it to friends.

I've re read this book and enjoyed it a lot more than the first time. This time around the story seems more coherent and the themes more urgent, more on point. The theme of inequality and the massive imbalance between the Zottas and the rest of the population seems to be a perfect reflection, almost prophetic, of the things we see in our lives every day.
