This was a delightful story with a sort of 'fake-boyfriend-for-hire'. 
 I really liked both Andrew and Spencer. Clearly, they have a lot in common and you can see their interest in each other growing. 
 Eli seemed kind of...flat. Like Spencer, I couldn't figure out what Andrew saw in him, when clearly Eli didn't really have the same interests, or seem to appreciate the same things Andrew did. (view spoiler)[and the whole the with the prints and the job application? It seemed like a stupid thing to do for Eli. Say, he had submitted the art and got the job, how could he hope to actually *do* the job if he isn't really an artist? (hide spoiler)] 
 I also liked Andrew's sister, Sarah, and all of Spencer's friends. 
 I look forward to the next book when it's released.
