I am too nice to give this book 1 star. It does have numerous basic patterns in it, and an instruction section, and it's nicely designed. But it has too many problems for me to recommend it, and I would certainly never purchase a copy for myself or anyone else.
Other reviewers have touched on the main issues: the uselessness of many of the projects, and the lack of photographs for every project. Nobody, but nobody, needs a beer cozy or a knitted paperweight. The only photographed sweater design in the book is unattractive (I might have revised this opinion if it had been shown on a person, but as it is shown in the book, it simply looks like it would not be flattering to many people). Many of the more important patterns are left to the imagination, with no supporting photos. So there is a photo of a dishcloth (essentially a knitted square in a single color) but not of a much more complicated poncho. Furthermore, there are too many patterns in this book for things like dishcloths, and the potentially quite terrifying "knitted curtain" (nevermind that knits really shouldn't be hung, and tend to droop thanks to gravity), and not enough to get excited about.
I don't know how it is that publishers don't get it through their heads with the consistent criticisms of every knitting book with this problem: knitters want to see pictures for every single project in a book, and if it is a garment, they want to see it on a model. If every project is not photographed and garments are shown flat or on hangers instead of on models, reviews of a book will generally be less positive than they might have been otherwise, period, and more-experienced knitters will habitually steer newer knitters away from the book in question.
Percival has a sweet and friendly tone throughout the book, and that may be the best reason to pick it up (in fact, one reason I gave this book two stars rather than one was pretty much for the same reason that you never tell your friend that you really hate her beloved new dress - fear of breaking her dear little heart). Other than that, give this one a miss and look into "Hip to Knit" or "The Yarn Girls' Guide", both of which have a variety of interesting projects and instructions for beginners.
