Yep. It's overtly American, a bit spoddy and focused a bit too much on US varieties of chilli (plenty on Numex strains for example), but by gum it's a polished, authoritative tome. Highly detailed, useful sections on plant care and chilli history, plus a goodly number of decent, useful recipes and helpful preservation hints.
I bought it that and Dave Floyd's UK book (more relevant chilli guide to UK strains perhaps, but lighter and with a tacked on recipe section of dubious use) for about £20 all in from Amazon if that's any help. It's a good read really - if you've any love of chillis there's a good chance you'll find more than a little to interest you
