In PLATO AT THE GOOGLEPLEX, Rebecca Newberger Goldstein set out to showcase, in sometimes startling ways, the continuing relevance of a classic philosopher. But what's remarkable is that she actually brings off this tour de force with both madcap brilliance and commanding authority.

Many readers simply can't stomach fantasy. They immediately picture elves with broadswords or mighty-thewed barbarians with battle axes, seeking the bejeweled Coronet of Obeisance ...

Once we know the plot and its surprises, we can appreciate a book's artistry without the usual confusion and sap flow of emotion, content to follow the action with tenderness and interest, all passion spent. Rather than surrender to the story or the characters - as a good first reader ought - we can now look at how the book works, and instead of swooning over it like a besotted lover begin to appreciate its intricacy and craftmanship. Surprisingly, such dissection doesn't murder the experience. Just the opposite: Only then does a work of art fully live.
