I haven't read any anarchist books myself yet, but I have read plenty of shorter texts I found online (mostly from The Anarchist Library).
Here are a few I found to be worth a read (in no particular order):
Since you already read The Conquest of Bread I decided to leave out most of Kropotkin's shorter texts, as I assume that you should already be familiar with his ideas and principles.
Although not anarchists, I still find many libertarian Marxists to be pretty insightful as well (some may as well be Anarchists in denial).
Anton Pannekoek's and Rosa Luxemburg's works being some I really enjoy reading.
I also have What is Anarchism? (by Alexander Berkman) and Anarcho-Syndicalism (by Rudolf Rocker) standing on my bookshelf, but I haven't gotten around to reading them quite yet. If they sound interesting enough you could give them a try.
