Adriana Messi has been through hell and back, not literally. (At this point that needs to be specified because you never know with some books) She's found a long lost twin, fallen in love, been kidnapped, taken on a second identity, fake dated someone who she started to fall in love with, joined a men's soccer team, made a name for herself on the soccer field, had her heart ripped to shreds, revealed her secret identity, and last of all, swore to never fall in love with a soccer player again.
And if you have no idea what you just read, then I recommend you read the first book.
Well, she was transferred to Barcelona to play soccer but refused to play the end of the season with them. It was too soon. Because the last time Adriana went to an official soccer practice, Cristiano Ronaldo ripped her heart into little shreds.
No more falling in love. Bad things always happened.
That's what she promised to herself.
But, sometimes, promises are broken.
