If you're interested in political risk insurance -- purchasing it, or working in the industry -- this is your book. It's a readable guide to the various covers available, the underwriting markets, the underwriting process, and includes a detailed review of various important policy terms (clauses) and what they mean. It's by Dan Wagner, a political risk broker and underwriter, so you won't get too much of the "against" side -- but as a survival guide to getting a decent policy, or a training manual for new brokers/underwriters, it's valuable.
