Dead Guy Spy (Nathan Abercrombie, Accidental Zombie Series #2) Book

I started reading this book and I arrived at the part where Nathan, the main character, has a secret identity of a zombie and no one except his two friends know about it. Later he figures out he has a spy following him trying to find out who Nathan really is and what he is capable of doing. Nathan and his two friends are being very brave, even at the most scariest moments in the book.
Nathan's friends are always there to help him face his Zombie life and still like him for what he is. I think the theme is that Nathan's freinds are always there for him, You can tell by how the author is describing his friends as always being there for him throughout the book. I can relate to him because I also have friends that are always there for me as I am for them.
This book is teaching me a lot about friendship even though it isn't about it. I am eager to find out what the spy wants from Nathan and what will happen when they meet face to face.

I just finished reading the part where Nathan, who is half a Zombie, met with BUM a secret agency that agrees to strengthen his bones so he won't break them since he can't feel any pain. Nathan had to agree to let BUM test some
things on him for an unknown science secret that BUM is working on. I was excited to read that Nathan's friends Mookie and Abigail are spying on BUM to find out about their science secret before letting them do tests on Nathan. I think they are going to find out BUM's secret and figure out why they are keeping it from Nathan.
This reminds me of the time in 2nd grade when I wanted to find out why my parents went to bed later than I did. I figured out because they are adults and no one can tell them what to do except themselves. I hope Nathan and his friends don't get into a bad situation if they find out BUM's secret. I am looking forward to finishing this book to see what happens to Nathan and BUM.
