   Without looking Lav knows she’s been given Saul's folding bone, the little stick he used for bookbinding. She rubs the worn ivory across her cheek. “Have a cup of tea before you go,” her mother says. Lav takes a cup and they sit, one on either side of the table that resembles a roughly hacked block of ice. She sips the tea slowly, holding the folding bone and the letter, muttering awkward thankyous.
