Once, in sleep, two boys breathed in perfect rhythm. But the once unbreakable bond between identical twins Jacob and Jonathan Rosenbaum has become as tenuous as their futures - their adult estrangement as seemingly irreversible as the convictions that separate them. Now twenty-four, Jacob is a gay activist living in Boston; Jonathan's wholehearted embrace of Orthodox Judaism has taken him to a yeshiva in far-off Jerusalem. In the shadow of his best friend's death, Jacob travels to Israel in the hope of reconnecting with his brother. It is a journey that will bring together two lives that are worlds apart and force Jacob to reexamine his sexual and religious identities, as well as his place in his complex and haunted family history. An unexpected arrival proves the catalyst for an ultimate confrontation between Jacob and Jonathan, as it lays bare the shattering secrets of a legacy that began during the Holocaust.
