The interview covers the whole of Legion history, not just the book, and is well worth reading. Interviewing Tim is CBR's Andy Khouri, who does an excellent job, as always.
The book is a big collection of essays, from scholars, fans, and comics creators alike. It'd edited by Tim (Grant Morrison: The Early Years, available in comic stores now), and it sports a foreword by Matt Fraction, an afterword by Barry Lyga, and a copia of essays on the whole history of Legion.
The book is currently in Previews for November ordering (order code NOV084474). For more information, click here.
We here at Sequart are grateful to the good folks at CBR (where Tim is a reviewer!) for the coverage!
