Evie Jenkins didn’t know what she was thinking by agreeing to switch places with her American heiress cousin. After all, she’s naught but a poor―and usually quite sensible ―companion. All she has to do is spend six weeks among London society, pretending to be an heiress…and ensure that absolutely under no circumstances does she accept any proposals of marriage. When his cousin declares himself in love with a new woman visiting from the States, Alexander Trenton―the sixth Duke of Hargrave―is determined to prove that the young lady in question is just another American "Dollar Princess" desperate for an English title. She seems innocent enough, but Alex is determined to expose her…by thoroughly seducing the lovely and fiercely intelligent heiress himself . What he assumed would be just one simple kiss erupts into something wild, uncontrollable, and much too public. Now the duke must save her reputation with a betrothal…little knowing that his charming Princess harbors a secret that would certainly ruin them both.
