This book was okay, but not for me. Telling it in present tense made it hard to provide any space for emotional reflection. I couldn't understand why Pen and Xander were initially attracted to each other apart from their physical proximity, which made it harder to invest in their nascent relationship. The author was touching on some big, important issues, like mental illness and being undocumented and searching for family, but she didn't spend enough time showing those and instead used up more real estate showing the inner workings of a restaurant staff. So there were plenty of scenes showing the staff misbehaving (to the point of redundancy), but not enough showing the emotional depth and complications that come with things like mental illness, being abandoned by your parents, separately, and being undocumented.
Additionally, this book's protagonists were out of high school, so it may be better to label this New Adult instead of YA.
There were some really standout scenes, especially when the author skewers the insidious ways racism is always around us. And I enjoyed the cooking scenes (more of those, they were great!). But even though I wanted to love Pen and Xander, and even though I knew what they wanted and what motivated them, I just couldn't connect emotionally with them, which was a bummer.
