The Iron Lance (The Celtic Crusades #1)

A Scottish boy travels to Jerusalem to try to regain his family's stolen lands, and ends up saving the relic Iron Lance that pierced Christ's side. Rich in heroism, treachery, and adventure, The Iron Lance begins an epic trilogy of Scottish noble family fighting for its existence and its faith during the age of the Crusades—and of a secret society whose ceremonies will shape history for a millennium.
