Nora Roberts - A mágia diadala

After a disease called the Doom destroyed civilization, magic became commonplace, and Fallon Swift spent her youth learning its ins and outs. Fallon cannot live in peace until he frees those persecuted by the government or the fanatical Warriors of Purity. He is determined to save even those who, out of fear or weakness, have become complicit in this evil... if they can be saved.
Strengthened by his bond with Duncan, his fellow warrior, Fallon has already managed to save countless shape-shifters, elves and ordinary people. Now you must help them heal... and rediscover the light and faith within themselves. Because even though he is the chosen one from birth, he is still only one person. And now that he's facing an old nemesis, setting his sights on an enemy stronghold and fulfilling his destiny - to restore the mysterious shield that once protected them all - he'll need an entire army...
