Historical Tapestry, one of the best historical fiction book blogs on the web, gives a great review to I Serve. The reviewer writes:
"This is a story about following a code of honour, the code of chivalry, about being virtuous, being true to God and to their Lady. Rosanne E. Lortz wrote an intelligent and engaging tale based on real characters and events that made this reading journey one of the most exhilarating of this year. Historical fiction doesn't get much better than this. Grade: 5/5"
