First book of the second trilogy in Terre d'Ange - it's the story of the teenage years and start of adulthood of Imriel, stepson of Phèdre, who leaves Terre d'Ange to go study in Tiberium. A very nice first book for a trilogy, a nice mix of old and new characters, and a good successor of the first trilogy (and since I liked the first trilogy a lot, well, I like this one too.)
