How's this for dedication? You spend two decades doing research for an extended biography of John Lennon, then plan to spend two more decades writing it—in nine volumes!
That's been Jude Southerland Kessler's project. And if that's not audacious enough, you decide to make the books historical novels (sort of), full of anecdotes by Lennon and the Beatles—most of which are so well documented that it can't really be called fiction. In fact it defies categorization.
Well, two of the volumes are available, so you can decide for yourself what they are: Shoulda Been There (2008) and Shivering Inside (2010), covering Lennon's life up through April, 1963. (The latter is simply the most compelling Beatles book I've ever read.)
Here's the first half of my interview with Jude, edited for blog brevity.
