After that they spent four years in Jerusalem to reconstruct the birth of the State of Israel for the book O Jerusalem!. Lapierre is proud that after spending a great deal of time in Jerusalem he knows each alley, square, street, and building in the Holy City intimately. Two of Lapierre's books – Is Paris Burning? (co-written with Larry Collins) and City of Joy – have been made into films. Lapierre and Collins wrote several other books together, the last being Is New York Burning? (2005), before Collins' death in 2005.
