"This Is So Not Happening" follows its preceding books along with its drama.
I don't know about how this books were for others, but this was not my favorite book out of the entire series (and I really did love the first two).
(Spoiler down below! Read at your own risk!)
Ally's and Jake's relationship hits a major roadblock when it was revealed that Chloe was pregnant with Jake's child. The fact that Ally stayed with Jake despite the fact that he slept with Chloe is a true testament as to how Ally loves Jake, especially since Jake was treating her quite badly in this book (if you've read the book, you'll see it--if you haven't, you'll understand the second you read it). He was rude, obnoxious, conceited, and only thought of himself.
How did Ally stick with Jake, especially when Lincoln (the "cute guy" she met in the school play) was so sweet to her? His character was the complete opposite of Jake, and was the guy that Ally needed after everything Jake put her through.
The girls in the novel: Ally, Annie, Shannen, and Faith, did a great job growing up (from the first book to now). It was nice to see the character development for the girls (and to see them get along and share some bonding moments).
The guys on the other hand, I had a hard time believing that they were seniors. Hammond spent half of the novel shoving and pushing Jake because of the grudge he held against Jake for getting Chloe pregnant. The idiot twins--well, I'm not shocked that they were acting juvenile, since they were juvenile in the previous books.
Jake, on the other hand, gave me mixed feelings. At first, I felt sympathetic for him because his life was going downhill the second he finds out that Chloe's pregnant with his baby. Then he started putting Chloe and the baby before Ally, which was okay for me--because it's his child and he should be giving Chloe and their baby some attention. But the way he's handling it ticked me off. It's quite obvious that he was totally more focused on the baby than his supportive girlfriend, who needed some attention from him too. She was going through her own problems too.
Soon Ally and Annie put two and two together and realized that Will might be the father (something readers knew/guessed since the last novel: that Will might be the father since Chloe and Will spent so much time together during the summer). Ally gets her hopes up and tells Jake this, only for Jake to get angry at her and shoot her down. By this point, it's obvious that Jake wants to be the father of the baby. He gets defensive and protective and yells at Ally. He's in a state of denial, since he can't accept the fact that Chloe might have slept with somebody else (Will) besides him. I'm surprised that he didn't realize that Ally was just looking out for him--but then again, he was in love with the fact that he was going to be a father.
So when the real father was finally revealed, Jake gets all "butt hurt" over the fact that he wasn't the father. I was glad to see him angry at Chloe, since her reasons for picking him to be her "baby daddy" was slightly kind of selfish--but my dislike for him grew when he, along with a Hammond and a few of their friends heckled her and shouted obscene, rude things at her. (One of them shouted, "moo!" at her). The boys had a fun time cackling over it. It's nice to see Hammond and Jake finally bond, but over the fact that they both hate Chloe? Not so nice or great. It's such a shame that the author had to ruin these two for me. I actually liked Hammond and Jake in the first two novels up until this point.
Jake also gets mad at Ally for defending Chloe, because she's supposed to "side with him" since she's his girlfriend. Last thing I remember, he wasn't even really there for her the entire novel so why is he so surprised when she's defending Chloe? Is there some kind of a double standard going on here? That she always has to agree with him and be there for him, but not vice versa?
If I was Ally, I would have defended Chloe too. Sure, Chloe has pulled some bad moves (like her decision to pick Jake as the "baby daddy") but she was just scared. She didn't pick him to be her "baby daddy" because she hates him or anything. If only Jake realized this instead of jumping on the "I hate Chloe" bandwagon right away.
In the end, after all the drama that Jake and Ally endures, they get the "happy ending" that the two of them deserved. I'm glad that they finally get their happy ending, because it's obvious that the two of them do not need any more drama in their lives.
