I don’t get it

I honestly do not understand this series at all. To be fair I can only half listen to this book because it is so bad. I will say it is just the smallest bit better in writing style than the first but that still doesn’t make it good. There are so many plot holes in this book it is amazing. Why did we even learn anything in the last epilogue for it to not even show up until we are half way through the book? Why do we start talking about things that are supposed to be kept secret in front of Ben? Why can demons sense angels but angels cant sense angels? It truly baffles me how much we are missing in this book. Honestly why are the friends even in this book? I don’t care about their lives at all so just don’t make them a point in these books. Why is the main character obsessed with her guardian angel? Why does he have a thing for her grandma…? Why is Ben so creepy and we just kind of brush past that? So many questions that I basically miss half the book because it is so odd.
