The Lovely Liar [EPUB ebook] 

Two fair-haired, blue-eyed beauties named Noella whose destinies are intertwined before they’re even born… One lives the high life in Europe with her mother and her rakish lover while the other leads a sheltered, quiet life… Until, alone, penniless and desperate, a beguiling stranger lures her into a web of deceit from which there’s no escape. Posing as her now-dead namesake, Noella Wakefield ingratiates herself with her estranged 'brother’, the handsome but bitter Earl of Ravensdale. Too late, she realises that she is part of a murderous plot – and then, after saving him from a dagger-wielding assassin, she realises she’s in love. But how could the Earl ever love a liar? And how can true love be based on a lie?
