Legends of the Ells 2 The Young Guardians

The saga of the Ells moves up a gear in the second book.
The excitement continues with a gigantic tsuani wave, the entrance of Xyle, the most dangerous terrorist of any age, a breathtaking ski-run escape high in the Himalayas and an attack on one of the world's biggest dams. Events move beyond Earth to a similar planet where Xyle is wrecking chaos and the powers of the young Guardians are limited.
