Song of Valeros

Heat shimmers on the Andalusian frontier. 
Apparitions of saints manifest amid treachery and tragedy. 
War drums pound, echoing up the valleys where Moorish farmers and Berber mercenaries stand ready to resist the Christian invaders. The starving armies of Castile and Aragon are unable to find a path into Andalusia. 

The future of Europe is at stake, driven by the hope that old-fashioned honor can defeat evil ambition. Meanwhile, Tomas is spying deep in Andalusia for Pedro d'Aragon. Isabella of Valeros and a confraternity of Occitan knights gallop into a trap set by the Crux Lunata to destroy Pedro. What's crucial for victory and safety? 
A general's pet djinni. 
A Celtic soldier-troubadour. 
A resurrected noble woman. 
A monk, accidentally turned renegade. 
A young Catalan soldier, battle-ready but lonely. 
A Moorish mercenary, spying. 
A heretic eager to get home.

Song of Valeros, Book 4 in the Accidental Heretic series, continues the adventure from Book 3, Crux Lunata. Valeros warriors race against time to join the Aragon army in Andalusia during the Reconquista in 1212.
