I can't believe I finished it - I didn't want it to end. Solomon, Lisa and Clarke are my favourite people. This story was amazing. Can I re-read straight away ?? 
 Full Review to come because I am just full of happiness and laughter and reminiscing every memory I have of every chapter in this book. It was just sooooo good 
 First Appeared on The Aus. Library 
 After finishing Highly Illogical Behaviour the first thought that came into mind was, "What a time to be alive!". Highly Illogical Behaviour was hilarious, lovable and now has a special place in my heart. 
 The cast of characters are so genuine and great, that reading their chapters felt as if I were conversing and listening to friends. One of out protagonists, Solomon, is the kind of person you immediately gravitate towards because of their sarcastic jokes and their sly humour. Solomon's growth throughout the book was something I was really proud of, as if seeing a friend slowly get back on their feet. Lisa with her perfect grades and selfish end goal had me on edge. It was the implication of the book but it was hard to swallow the possibility of a falling out between friends, because Lisa was really there for Solomon which inevitably made me adore her. If you put aside her selfish goal, she's really a great person, a decent one and an actual likeable character. We see her push aside her own self interest and actually help Solomon throughout the book. The last character who's apart of the fantastic trio in the book is Clark, Lisa's boyfriend. He's just a down to earth character who, I have no doubt in my mind, everyone will automatically love. 
 What I loved about Highly Illogical Behaviour is that all the characters are important and are there for Solomon. Solomon's grandma was an amazing addition to the cast of characters. She was always there for Sol and so were his parents. The relationship Solomon has with his family is just extraordinarily beautiful. John captures the essence of parenthood through Solomon's parents, who protect their child and do whatever is necessary to make him feel safe and comfortable. 
 Solomon's agoraphobia was extremely interesting to read about. I've never come across this specific mental illness in YA and having John introduce it to me was incredible because I was never aware of it ever existing. John strips away the stigma surrounding mental illness through humour and great conversations between friends, which in turn create beautiful memories. He strips away the stigma through a story that seems utterly real and through friends and family who are supportive. John's research on the mental illness was well informed and well written. 
 The dialogue within the book is hilarious. It's what really kept me going and intrigued me even more. I swear, Solomon is a comedic genius along side Clark. Their conversations about "Star Trek: The Next Generation" are both interesting and hilarious. 
 The story itself was also very unique. We peer into the lives of all three teenagers and we read about why they're the way they are. We see the awkward moments of new born friendships and the first crushes to be formed which are uncontrollable. We see jokes cement these friendships and jokes making them more than friends but family. I just can't put into words how much I really love these characters and their stories. They really were an amazing bunch of people. 
 The title of the book itself questions the actions of Lisa and Clark not just the way Solomon was told he was thinking by his father. Highly Illogical Behaviour is a coming to age story. We see Solomon grow and love and be brave. We see him do things he'd never thought he'd do. We see him happy and that is why I truly loved this book. 
 Highly Illogical Behaviour was refreshing and a book hard to put down. I cannot tell you guys enough how hilarious and enjoyable Highly Illogical Behaviour was. I just need you guys to pick it up and devour it and all it's beauty. John has written a book that has made me happy and laugh out loud in public. He's also potentially made other readers do the same. I hands down had to give this book 5 stars. It's just too good, one that is so underrated.
