I'm guessing this is one of the better synopses of Kropotkin's political beliefs that you'll find out there, short of actually reading his work.
Not a biography, in case you're looking for that. It's an essay collection, with Morris going theme by theme reflecting on Kropotkin's thoughts on each: The French Revolution, anarcho-syndicalism, ecological anarchism, etc. Morris goes into a some biographical detail but the book is definitely not comprehensive in that regard.
The Politics of Community is an uneven mix of well-presented and measured analysis of Kropotkin's political thought--as well as comparisons to his detractors, his antecedents, his successors and those who bastardized his work for their own ends--on the one hand and odd, almost jilted-seeming critiques of Kropotkin critics on the other. Like a weird wavering between rigorously scholarly text and spiteful denunciations.
There's a fair share of typos, nothing earth-shattering, but enough to make me wonder if this wasn't sufficiently proofread.
