Warrior's song / Catherine Coulter.

Enhanced descriptions from Syndetics:

Dear Reader: Warrior's Song was originally titled Chandra and was first published in 1984. I've changed the title because, as the lead novel of the song series, it was time for this book to clearly join its cousins and adopt its rightful name, thus, Warrior's Song. I haven't done any rewriting, just designed new clothes that will tie all four medieval novels together. Chandra de Avenell was a girl raised as a boy and thus, in the thirteenth century, a warrior. All she knows is freedom and independence. This leads to big problems when her father forces her to marry Jerval de Vernon, a noble young knight who has the misfortune to want her for his wife, and no other. Things have reached a very low point indeed when Chandra and Jerval journey to the Holy Land to join Prince Edward in his war against the Saracens. In this alien place will Chandra learn that there are many kinds of strength? That sharing with another person-both joy and pain-is more precious than her warrior's unbending pride? You meet Graelam de Moreton in Warrior's Song. You'll see him next in Fire Song, the second of the Medieval Song quartet. Do let me know what you think of Warrior's Song. Write me at P.O.
