Is a book worth killing for? In The Book Stops Here , by Kate Carlisle (Obsidian, $24.99), bookbinder Brooklyn Wainwright may learn the answer. She’s scored a sweet gig as a guest appraiser on TV’s popular “This Old Attic.” In one episode, she estimates that the value of a first edition of “The Secret Garden” could “feed a family of four for at least two years.” The vintage copy was submitted by Vera, who bought it at a garage sale for $3 and giddily anticipates turning her find into fortune.
