Beautiful Katherine Collins, a girl from nowhere, suddenly had it all. Her promising career as an up-and-coming cabaret singer in a swinging 1930’s hot spot known as Simply Blues lands her smack in the middle of a tug of war the likes of which she'd never dreamed possible. On one side stands the man who had opened the door to her career but who refuses to allow himself any further claim to her heart, and on the other stands a man who will do anything to claim Katherine as his own. Set in the tumultuous times leading up to World War Two, both men will shape her destiny in unchangeable ways, but whose heart will Katherine choose, and whose will she break forever?
