What If It's Us by Becky Albertalli and Adam Silvera.
Genre: Contemporary YA romance.
Short Summary: Two boys meet at the post office and fall in love.
My rating: 3/5 stars.

Plot:
I think the main reason I didn't enjoy this book as much as I could have is because the whole plot is 100% romance (and a sappy romance at that), and I don't really like genre romance novels. I guess the plot was fine for what it is, though.

Characters:
I could barely tell Arthur and Ben apart. I kept getting them mixed up, to the point where I kept forgetting whose POV I was in.

Also, both Dylan and Arthur seemed creepy to me. Dylan called a girl he just met his "future wife" and Arthur was very stalkerish. Ben was okay though, if a bit bland.

Writing:
There were Harry Potter references everywhere, which got a bit annoying, but otherwise the writing was all right.

Other:
Here is where I appreciate the diversity. We have a gay Jewish boy with ADHD, a gay Puerto Rican boy, and a side character who is biromantic ace.

Would I recommend it? Maybe, especially if you like books that are 100% romance.
