Read all of my thoughts and my full-length review here 
 This entire novel takes place over the course of twelve hours. Which is precisely how long it took me to read it. 
 This is far more than the boy-meets-girl that it is initially set up as. Yoon cleverly uses a burgeoning teen romance as the catalyst that sets a series of lives in an unprecedented motion, which perfectly exemplifies the butterfly effect: the concept that small causes can have a greater and unforeseen impact on something previously unrelated. The story is interconnected with fragments of others' lives that touch on the main narrative, despite their initial quasi irrelevance. Small events ripple outwards and everyone's lives become collateral in the process. 
 Dealing with issues such as cultural identity, race, racism, fate, religion and finding your fit in the world, this is an impactful and harrowing story that had me laughing and crying the entire way through!
