I need to admit that The Memory Book has the potential to be a fun emotional read. I even enjoyed the first-half of the book! But the second half? Brace yourself since this review will contain rants about how Avery messed up with the second-half. 
 Or at least, just for me. 
 The Memory Book tells us a story about Samantha who's diagnosed with a rare disease called Niemann-Pick Type C. I've never heard about that disease before. So, I googled it and read several explanations before reading the explanation in the book. And it turns out that this disease has 'dementia' as one of the side-effects. 
 After knowing that this book contains a disease with dementia, I lower my expectation. I didn't expect to bawl my eyes out after reading this book. I mean, it's hard to make someone cry over a book. So, better not to expect something than being disappointed in the end, right? 
 Well, I need to say that I fuckin love the first-half of the book. Samantha is a quirky, lovable, funny character. Her characterization simply stands out and make it hard for the readers to resist her charms. And her relationship with her crush is soooooo cute. Heck, I ship them so much. I love how their relationship develop little by little. It feels innocent and honest. It feels real! I couldn't stop smiling throughout their interactions, dates, or over simple conversations. I love them so so so much. 
 Then, I moved on to the second-half of the book. 
 Where shits began.... 
 First of all, I lost the 'Samantha' that I love. She changed a lot and I couldn't see the quirky and innocent Samantha that I knew before. I know, I know. I didn't expect her to still being funny and lively while the death haunts her. But she has just changed into a bitch. I'm not even kidding. She's a bitch. A self-centered, short-sighted, bitch. I still and will NEVER forgive what she has done in the last part of the book. She deserves the end that awaits her from the begining. 
 Secondly, the focus suddenly switched into romance. I mean, the first-half balance the ratio between romance, teen life, and illness pretty well. But the second half? I believe that the second-half supposed to focus more on the disease. Since Samantha's disease is getting worse day by day. But no, the author suddenly wanted to add a 'first-love' conflict to the story and bam! Bye-bye Niemann-Pick type C that now feels like being used only as an accessory. 
 Samantha's disease feels a bit romanticized and I doubt that the author did a proper research before. Because I expect a 'real point of view' of how people with Niemann-Pick Type C live, how to take care of them properly, what kind of special treatments that they should receive, etc. But no, the author decided to focus more on Samantha's love life that works perfectly fine despite she has a disease she needs to take care of. 
 I cried a bit on several scenes of the first-half. But the second-half tortured me like hell. 
 So, I could only give The Memory Book two generous stars. Yes, it's a generous rate since I nearly couldn't stop myself from smashing Samantha's head on the wall and speed up Samantha's dead. The second-half destroys everything that has been built up inside me and I just couldn't forgive Avery for that. 
 By the end of this book, I feel so angry because a book that has so many potential to be one of my most favorite book ended up to be totally disappointing.
