Out of Anna, Lola, and Isla, I really felt a more personal connection with Isla. I've been where she was at, hopelessly crushing on a boy. Unlike me though, Isla managed to snag the guy, Josh, though it was a bumpy road for the both of them.
The relationship between Isla and Josh was cute, though not flawless. Isla saw herself as not deserving of Josh which causes problems, though she isn't the only one to cause problems. The first draft of Josh's graphic memoir has some unflattering pictures of Rashmi and a lack of pictures of Isla. Isla becomes extremely disgruntled, which is totally understandable because the way Josh depicted Rashmi made her seem like a goddess in comparison to Isla. They manage to work out their snag though and become a great couple.
Now with this series, I usually don't have any cons, but with Isla I do have one, though it is nothing major. In this book, there are a few sex scenes and countless making out sessions. While this is typically not a problem with YA contemporaries, I felt like they weren't necessary and out of place, making Isla and Josh's relationship seem more physical than emotional.
Overall this book was splendid. I'm sad the series is over, but I'm sure Stephanie Perkins will continue to give us great work.
