This is a fairly short "business novel" in which Eli Goldratt's daughter explains Lean and Kanban using Theory of Constraints terminology, by re-hashing most of what's in Goldratt's earlier 'Critical Chain'. I suppose some of the ideas might be new to some people, but there's nothing really important here if you're already familiar with Lean and Agile. And the "novel" is pretty thin on the ground, with little of the allegorical story-telling that made 'The Goal' so wonderful.

In a word: lame.
