Lightly, an impossibly good-looking star quarterback from an elite Virginia college, drags along an unlikely sidekick-the immensely unpopular and overweight Santana Montana-to a remote Costa Rican fishing village in search of a unifying vision-a secret location where he might glimpse the parallel universes predicted by quantum physics. Informed by quantum theory and driven by the desire to outrun the dark grip of family trauma, Lightly sets out on an impromptu picaresque adventure that is at once absurd and poignant.
