After the Alpha Cru reaches Rome, they return home to the Crucis. Alea and her friends face greater challenges than ever before. How can they stop the Gretzers, who are dumping toxic industrial waste in the Tyrrhenian Sea? And what help comes from the realm of the mermaids? The destruction of the sea reaches unprecedented levels, and the major climate concert in Rome becomes a test for the Alpha Cru. Can the friends contribute to the urgently needed change in mindset with their environmental songs? They risk nothing less than their lives with this performance, as Doctor Orion is after them, and they are practically presenting themselves to him on a silver platter. Will he try to capture the Cru in the stadium? With a sense of camaraderie, music, environmental activism, and an unprecedented glimpse into the world of the Magical, this first part of the ninth volume promises guaranteed reading pleasure.
