When Sloane returned to the Rivers house , the sound of piano music floated down from the second floor . She didn't even have to guess - it had to be Samantha practicing in the piano room . To be fair , Samantha was talented . Otherwise , she wouldn't have had the guts to announce so early that she was going to study under the famous pianist , Jack Bernette . But Sloane didn't want her getting too full of herself . When it came to the marriage alliance between the Hawthorne family and the Rivers family , many people shared Adrian's view - they thought it was just a temporary arrangement from the Hawthornes . Still , there were always a few self - important " smart " people eager to suck up to the Rivers family . Marshall took full advantage of it and basked in his newfound status within the Rivers family . Sloane , when she found out , simply smiled . The higher he climbed , the harder he would fall . Sloane decided to let him enjoy it for a few more days . Two days later would be Samantha's 18th birthday . The Rivers family was planning a huge celebration for their precious daughter , sending out invitations everywhere . Not a single person remembered that Sloane and Samantha had been born on the same day . Send Gifts
