I love spy stuff and I like it dark and gritty. This was totally the opposite. While the book was well written, I found the plot and characters too fluffy and unspy like. They weren't in any way realistic like Verity in Code Name Verity or Alexandra in They Call Me Alexandra Gastone. If you're into books that are spy lite then this one might be for you. It's more tongue and cheek and caperesque then spy. I guess it depends what you're looking for in a YA spy book.
