Latest book I bought? Hmmm, probably CJ Cherryh's 'Regenesis' (sequel to Cyteen). Still my current author-obsession. Read/borrowed a lot more since then, though, most recently Stephen J. Gould's 'Dinosaur in a Haystack'. Hey, if you're going to be into sci-fi you've got to know your sci. I'll admit I occasionally leave my books face-down for short periods of time to mark my place (but only a few minutes, not hours - then I'll find a scrap of paper or something!). But dog-earring, never. That just rubs me completely the wrong way. Got to love your books, I have been known to clasp one to my chest and give it a kiss on occasion I admit.
