I'm honestly waffling between 2.5 stars and 3. I liked Hello, but it made me sad to read, and I don't like to be sad when I read. Not every character needs to be likable, true, but it's hard to root for Clare as a character and her relationship with Aidan when she really does spend half the book trying to break up and the other half hedging. And it's not fair to Clare that Aidan gets to be the romantic one. If their positions were switched, everyone would hate Aidan instead because he'd be a pretty douchey boyfriend. In fact, he'd be like Jason feom The Truth About Forever. 
 But anyway, there are definitely sweet and swoony moments, but I'm just not sure this concept really worked. It's always fun to watch two characters fall in love on the page, and to some extent, that is present in Hello, but because its viewed via flashbacks, something is lost in the translation. It's more dull, flatter than if we were reading about Aidan and Clare's highlights as they occurred. It's like the reader is dropped into the middle of an in-progress conversation, which actually is kinda true, but it's pretty uncomfortablr, to be honest. And while I do think Clare and Aidan eventually pick the only viable option for them and while there is hope...I'm just disappointed with the book overall. I think this was a little bit of a misstep for Jen, although I totally forgive her and will continue to read all her books. Not every book published, even by popular and favorite authors, can be a home run. 
 Hello Goodbye and Everyhing in Between is fun and most certainly true to its title, but it lies heavily on the bittersweet side of romance, which will most likely prove to be a turnoff for most contemporary romance readers.
