Drawing on recent advances in knowledge, this biography shrewdly explores Marvell's complex and elusive personality.

As two clever boys exploit a clerical oversight, each one discovers new perspectives on selfhood, friendship, and honesty. Identical twins Ray and Jay Grayson are moving to a new town. Again. But at least they’ll have each other’s company at their new school. Except, on the first day of sixth grade, Ray stays home sick, and Jay quickly discovers a major mistake: No one knows about his brother. Ray’s not on the attendance lists and doesn’t have a locker, or even a student folder. Jay decides that this lost information could be very…useful. And fun. Maybe even a little dangerous.
