I really did enjoy or at least not hate the majority of the book.

The ending though...well, I didn't hate it. It just wasn't particularly satisfying.

I feel like I should've felt something when Teresa died, but, honestly, I don't feel like I knew her enough to. Most of the series was just spent making us either hate her or love her, but, throughout all that, I personally never felt that sense of attachment towards her.

I also feel like I should've felt something between Thomas and Brenda, but I didn't either.

I understand the actual ending, but I don't feel like it answered many questions, and this was a series that accumulated a lot of questions over time. I don't mind if the Immunes found paradise by the end; I just wish they didn't leave so many questions unanswered before they did so, or at least developed the characters enough to at least make me feel bad about Teresa's death and feel giddy about Thomas and Brenda's relationship, if that's what you could call it.
