Kings of America by R.J. Ellory
In America, kings are not born, they are made.
Danny McCabe isn't his real name. America certainly isn't his real home.
But now Danny finds himself fleeing Ireland for the bright lights of 1930s Hollywood with two virtual strangers, Nicky Mariani and his beautiful sister, Lucia.
As Lucia pursues her dream of stardom, Nicky finds his calling in the violent underbelly of the city of dreams. Torn between his love for Lucia and his desperate fear for their safety, Danny is drawn into a chain of events that will pit brother against sister, friend against friend, and lover against lover.
