Experimenting with cut-text

I'd prefer it to be the book's title, but then if I have more than one book (and, at the moment, I do) the titles disappear. Putting my next line in makes that vanish, too, and gives it a strange significance on the header page. Maybe numbers? Or repeat the title?

( Reginald Hill, Child’s Play. )

( Reginald Hill, Deadheads (re-read). )

( Reginald Hill, Bones and Silence. )

( Reginald Hill, Recalled to Life. )
