Look No Further, by Rioghnach Robinson and Siofra Robinson

Niko and Ali meet each other at an exclusive summer program for art students in New York City.  Underachiever Niko barely squeaks in on the waitlist.  Back home in California, art is his best subject but he's really more devoted to surfing than studying.  His mother and stepfather are white, but his biological father was Chinese. Showing up at the program, he's immediately pegged as an Asian artist, a characterization with which he is not fully comfortable.  

Ali is a local girl, a high achiever, and yet she feels out of place amidst the artsy types at the school.  She slavishly copies the other students in how they dress and even in the art they create.  She has little sense of who she is. 

When the two of them get assigned to work on a project together to trace how their heritage has informed their art, they quickly make a shocking discovery:  Niko and Ali have the same father!  Neither of them have ever met him, but with some research, they discover that he might be living in New York.  So, while trying to keep up on their studies, they decide to try to track him down to see if they can reconnect with him.  The search causes both of them to confront the parts of themselves that they are uncomfortable with and subsequently to grow.

Overall, this a well-written story about self-identity and finding oneself..  For Ali, this is the traditional  trope of discovering her own voice by ceasing to copy others.  It also involves her becoming comfortable  embracing her feelings for another girl.  For Niko, it is about connecting with his Asianess (raising several issues about anti-Asian racism along the way).  Either way, the novel has a well-paced dramatic arc and delivers a very satisfactory ending.
