I suppose by definition any memoir by Rebecca Solnit would be Solnit-esque. What that means in Recollections of My Non-Existence - which I of course enjoyed very much - is that we get the personal perspective combined with the philosophical and social concerns that animate all of the writing ... but somehow without a great deal of psychological interiority. Which is not exactly a criticism in this case but more a feature. I do think that much of the pleasure I got from this one was possible because I'm already in some deep with her writing and work.
