 In short: Every emotion and feeling that was incited in me while reading Isla and the Happily Ever After was felt strongly and sincerely, and I LOVED it for that reason. 
 Ohhh the complete and overjoyed happiness this book brought me!! I mean, all of Stephanie Perkins' books have brought me happiness and swoons and squees and feels, but I think it's possible that Isla and the Happily Ever After tops them all (though it has been quite a while since I read Anna and the French Kiss so I might not be remembering correctly). Isla left me in a puddle of feels and happy tears when I finished it in the middle of the night and I loved every moment of it. 
 One of the things I love most about Stephanie's characters is there is at least one aspect in each of her leading ladies that you can identify with. But I think Isla is the girl that I relate to most. She's shy and has low self-esteem and she doesn't know what she wants to do with her life. She prefers to read about adventures than go on them. Josh is her opposite in many ways and yet they connected and played off each other perfectly. I LOVED them together. 
 Of course it's no surprise that Stephanie Perkins got the romance right. She proved as much in Anna and the French Kiss and Lola and the Boy Next Door. But I was reminded again - and more powerfully than ever - that Stephanie Perkins has a way of pinpointing and recreating the feelings and the ups and downs of first love like no other author that I can think of. The intense giddiness, the unwanted insecurities, the extreme elation, the bitter and unreasonable feelings of jealousy, etc. - every heightened emotion you go through when experiencing your first love is there (or at least the ones that I went through...). Stephanie Perkins handles first love beautifully and meticulously. 
 Every emotion and feeling that was incited in me while reading Isla and the Happily Ever After was felt strongly and sincerely, and I am totally CRAZY about this book for that reason. I am unbelievably bummed that this trilogy of Stephanie's has come to an end, but I am also unbelievably ecstatic that Isla and the Happily Ever After was everything I was hoping it would be and that we got to see Anna, St. Clair, Lola, and Cricket one last time (because I love them to death). I look forward to reading whatever Stephanie Perkins writes next!
