A thoughtful book. I would say that it seems the title has been picked because it sounds cool, not for its relationship with the content. Many of the essays are about loss, or memories, rather than about being lost, or getting lost. Which was somewhat disappointing, since the first essay ends posing the question: `How will you go about finding that thing the nature of which is totally unknown to you?'. This is not the central theme. I can of course see how loss and being lost play off one another, but *getting* lost, *finding* the unknown; hmmm, not as much as is suggested.
But once you've put aside those raised expectations, once you realise this is not really her intention, it is mostly an ejoyable thoughtful read. Some essays are far stronger than others: illuminating and amusing on Klein, a fascinating alternative Vertigo, and the colour Blue permeates. Essays about her relationships, a lost friend (though terribly sad), and a rather poetically forced meandering about turtles did not work nearly so well. I've read she understandably hates being lumped in with the Haight Ashbury miasma, but you can see why she sometimes is.
Anyway, her questioning and seeking, her meandering tangents do indeed often illuminate and give pause for thought. It all speaks of sane person (at least, as sane as anyone one person might be). She has written more satisfyingly (Wanderlust and Muybridge), but this book is an easy going and pleasant companion.
