For many years, the standard prayer book to be found in American Orthodox synagogues was the bilingual one produced by the ArtScroll publishing house in 1984. More recently, it has faced competition from several editions by the Israel-based Koren press, the most popular of which features the translation and commentary of the former British chief rabbi Jonathan Sacks. The Rabbinical Council of America (RCA)—the main organization of Modern Orthodox rabbis in the U.S.—last year added another siddur to the mix. In his review, Yosef Lindell compares it to its competitors: 

On August 9, 2001, Ahlam Tamimi and Izz al-Din Shuheil al-Masri traveled from the West Bank to Jerusalem, where Masri detonated himself in a Sbarro’s pizzeria, killing seven children and eight adults, and injuring scores. When the two passed through an Israeli checkpoint earlier that day, they appeared to be a young couple; had Masri been alone, police almost certainly would have stopped him and discovered the deadly bomb in his guitar case. Tamimi was arrested shortly thereafter and sentenced to life in prison. Ten years later, she was among the 1,027 Palestinian prisoners exchanged for the captured Israeli soldier Gilad Shalit. She now resides in Jordan.
