Propelled into the public consciousness by the best-selling single of 2000, Siren returns to the world of rock music, and their brilliant comeback and stage show wows both the public and the critics alike. It seems fate has smiled kindly on the quartet and the future looks secure.

However opposition to Katie's stage act rear its head amongst some influential people in the States and their tour there falls under threat. Katie, though, is nothing but a fighter and take on the conservatives head-on, culminating in a public argument with no-one other than the President.

Katie's – and Siren's – reputation is made in the aftermath and on both sides of the Atlantic they become regarded as rock royalty. More hits follow and Katie's life seems fulfilled both professionally and personally. But just when nothing could seem to go wrong, an earth-shattering revelation plunges her into deep despair and threatens once again to rip the band apart.
