The Fern and The Cross — Barbara G. Tarn

A knight's tale of love and betrayal.

Almost killed by a brother-in-arms, saved by the enemy â€" a story of love and knightly duty around the third crusade. Robert and Manfred are brothers-in-arms who believe in courtly love. They pledge to each other like knights do, and go to tournaments, ending up in the retinue of Richard Lionheart. Then Robert marries Brithwen, an Anglo-Norman heiress, and when they both head for the Holy Land to free Jerusalem from Saladin, they must leave behind the lovely woman of their hearts.
