3.5 stars 
 When We Collided is so much more than a regular YA romance - it deals with profound issues such as mental health and loss, and is a moving story about family, friendship and acceptance. 
 We meet two characters who couldn't be more different: 
 Vivi is artistic, full of colors, emotions and expressions, a true whirlwind of a girl. 
 Jonah, on the other hand, is a serious, down-to-earth boy who tries to keep his head above water while caring for his little siblings. 
 I loved how Vivi's personality shone through. She is out there, but never a caricature, and despite her illness she still tries to stay true to herself. 
 The family dynamics of Jonah's home were a true joy to read. The interactions between siblings were hilarious and despite the fact that the family is facing so many challenges on a daily basis and barely keeping it together, the warmth and love they feel for each other is always present and evident. Their banter and fights were easily the best part of the book and they felt like a true family, along with fights, flaws and immense love for each other. 
 The story and the dual narratives were engaging and fast paced. I found myself unable to put it down and was completely captivated by Vivi's vivid persona and Jonah's chaotic, yet loveable family. 
 Why only 3.5 stars? 
 While this book is well written, it has a flaw that I simply couldn't overlook - instalove. 
 The characters meet and proceed to fall in love within a day. While it's easy to see why Jonah would be drawn to Vivi's free spirit and she to his stable, calm nature, it was simply too sudden and too fast to be believable. 
 I also found myself wishing that they weren't a couple. This book didn't need to become a romance and I feel like they would work much better as friends. The chemistry was lacking and I honestly thought that Jonah and Ellie would make a much better couple. 
 Other than the above-mentioned flaws, this book proved to be a perfect summer read. If you're looking for something fast paced, beautifully written and moving, look no further than When We Collided.
