Depending on your skill level, potentially a good book. For my first tile project (a bathroom floor + tub surround) I relied John Bridge's "Tile Your World," this book, and Michael Byrne's "Setting Tile"--roughly in that order of preference. I recommend all 3 as each has different valuable info. Books are cheap compared to your time & materials cost.
This book has the advantage of great photos and it's modern, unlike Byrne's book or Bridge's first (older) book. However, it definitely lacks key pieces of information and is quite sparse. You need to read, and reread, each section several times because the text is not written in a linear, step-by-step format. (Where was the editor?) I think it's more of an overview with ideas about design, tools, etc. than a clear "how-to" which the Bridge and Byrne books are. Numerous high quality color photos which are helpful for design and for learning some layout tricks.
Things I dislike: (1) minimal discussion of key things like how to mix thinset, the tub-to-tile junction in a tile surround, etc. I'm sure there would be more if I had advanced beyond floors and tub surrounds. (2) They should retitle it "Spend Like a Pro." Rather than tell a DIY-er what's essential vs. what can be done with basic tools, Meehan assumes that as needed you will drop $2000 on a Gemini Revolution saw, buy a DeWalt mitering wet saw ($1000), buy only Stabila levels ($$$), buy top-of-the-line laser leveling tools, buy a $60 A-square, use only Ditra, etc. These are great (and I do use Ditra too) but there are certainly cheaper ways to avoid. If this is your only resource, you'd never know about alternatives.
Do yourself a favor and buy this book but get the newer Bridge book and the Byrne book too. Also discover the tile forums on the web.
