When letter-writers need to insert a note after they've already used a postscript, what do they do? Add a post-postscript, or PPS.
Those three letters also apply to my reading plans this summer, which center on three simple topics.
Pirates. Poems. Sharks.
The pirates belong to former British poet laureate Andrew Motion, who continues the story of Robert Louis Stevenson's "Treasure Island" in his forthcoming novel, "Silver: Return to Treasure Island" (Crown, $24, August). Stevenson's classic cunningly leaves much unsettled at the story's end and now the children of Jim Hawkins and Long John Silver join up to continue the hunt for buried loot.
