Fantastical fiction of the very best kind, whether you want to call it SF or not. The blurb draws the link to the worlds of Philip K Dick but I was reminded more of The Catcher in Rye, with its confessional and curious diary entries, at least until a pivotal revelation half way through. The narrative turn that follows changes utterly the experience of this book and brings with it a growing and compelling tension. Borges, too, is frequently cited as a companion in fiction, but, once the machinations of Morel become clearer, I was reminded much more of Stanislaw Lem's Solaris, with its intimations of loss and its compulsion to repeat episodes of longing and connection with the slippery spectres of our pasts and imagined futures. Really splendid.
