The Pied Piper's children are back. But will they save the world or destroy it?

Unityfest is more than just a huge pop event organized by superdivas Tarina, B-Word, and Kalli, globally renowned as the Sirens, for the chart-topping trio are in reality sorcerers many centuries old and the event is a ruse designed to drain the very life from their millions of adoring fans, thus making the three veritable gods on Earth.

And the only things standing in the way of their grand scheme are a pair of bongos once played by Who drummer Keith Moon at a party...and one of the Pied Piper's abductees, returned to Earth in the unknowing form of child prodigy Raina Melendez.

Raina, who goes by Xyla, has no idea how she is producing virtually every drum and percussion sound from kettles to cymbals to wood block on a simple pair of antique bongos--and even less of a clue that she and those drums are likely the world's only hope as the Sirens put on the greatest--and deadliest--show on Earth.
