nobody is forcing you to read the book, and maybe it's not for you.
I found it very good; history of IPA in Britain (Hodgsons, Bass etc), and America where NE brewers in the 1800's were brewing Burton style IPA's aged 1-2 years before bottling (CH Evans, Ballantine, Frank Jones), with a brief brewing history of Canada, Australia and India, hop IPA became to be exported to India and other countries, through the decline in IPA's here due to taxation, in America due to prohibition, last century breweries (Allsopps, Barclay Perkins, Whitbread, Bass, Worthington, Younger's, McEwans, the American craft brewing revolution in the late 70's (what was going on here?), through to present day. Recipes from breweries for UK and US (49), with brewing techniques for IPA's, breweries information on mashing, boiling and fermenting. Analytical information, conversion units, large bibliography. What is there not to like?
