The last book in Oliver's Delirium series leads Lena eventually back to Portland. The chapters alternate between Hana and Lena until they eventually collide. The whole romance thing sort of gets resolved by just ending, which I am fine with, but if readers are on some kind of "team," they may be disappointed.
Like I mentioned in the first review of book one, I don't have any desire to read the other sub-books that came out about some of the other characters. I'm just going to let these characters go and I will believe what I believe as far as what happened after the end and what happened when the characters were not part of the immediate storyline.
