Tolkien, Simon, 1959- Theo Sterling duology #2

"Barcelona 1936. Theo helps the Anarchist workers defeat the army that is trying to overthrow the democratically elected government, and he is reunited with his true love, Maria. But all too soon, his joy turns to terror as the Anarchists turn on him, led by a rival for Maria's affection. Lucky to escape with his life, Theo returns to England to study at Oxford. But his heart is in Spain, now torn apart by a bloody civil war, and he is quick to abandon his new life when his old schoolmate Esmond offers him the chance to fight the Fascists. He is unprepared for the nightmare of war that crushes his spirit and his hope until, back in Barcelona, Theo is confronted with a final terrible choice that will define his life forever. As Theo's tumultuous coming-of-age journey reaches its end, can his dream to change the world--so far from home--still hold true?"--
