This Is So Not Happening is the satisfying final installment of the immensely readable He's So/She's So trilogy. It is important to have read both of the previous books to be up to date with the characters' paths up to this point. Just as Jake and Ally's relationship is poised to move forward positively, friend Chloe turns up pregnant, pointing to Jake as the father. With great strength of character, Ally values her relationship with Jake enough to do everything she can to be supportive. Jake is attentive to Chloe (attending prenatal/sonogram appointments with her), but in the process loses sight of Ally. Attention is paid to the discussion of how to proceed (or not) with the pregnancy. Ultimately, adoption is decided upon, and it is with great dignity that Chloe remains in school, openly pregnant, in spite of the hurtful gossip directed at her by classmates. Jake seriously ponders the concepts of fatherhood and adoption. Ethical questions and vitriol come in to play however as suspicion about the baby's paternity begin to pop up. Ally is distressed by her mother's impending marriage, but her fractured family situation returns to a comfortable place for her in the end. As in previous books, classism is a major theme. Teen sex is referred to, but not described. Jake and Ally's interaction is limited to passionate making out. Parents sponsor a beer birthday party at one character's home. Language is graphic, but not overly frequent (f--k, sh-t, cr-p, a-s, sl-t). Fans of the trilogy will be pleased with the ending.
