I was send this book by a publisher this past week and I'm very impressed by it. It's called "They Say / I Say" The Moves That Matter in Academic Writing by Gerald Graff and Cathy Birkenstein. Here's what the publisher says about it, which sums up pretty well its attraction for me:

"They Say / I Say" shows that writing well means mastering some key rhetorical moves, the most important of which involves summarizing what others have said ("they say") to set up one’s own argument ("I say").
