When we Collided is the story of Vivi, she moves to a new town for the summer as her Mum is an artist, it also doesn't hurt that she didn't want to see her 2 best friends after what happened. 
 Vivi quickly charms everyone around her and makes friends with the little coastal town. Jonah is tired and stressed out, having 5 siblings and juggling the family restaurant will do that to you. 
 Vivi and Jonah meet and instantly fall into like love but we quickly see everything's not okay with both of the characters and the story unfolds from there. This book does deal with mental illness and grief and I felt it tackled the issues and themes well. 
 I really flip flopped with my rating on this. I started at a high 4, went down to a 2, went back up to a 3, went down to a 2... you get the point right? 
 Lets start with the bad things first so we can end on a high note. 
 Dislikes: 
 - Jealousy. I hate Jealousy in my female characters, can't we all love one another? 
 - No one really taking notice of what was going on, I mean their were OBVIOUS signs (view spoiler)[ she told her freaken mother she was only taking one pill, and her mother has obviously been told what a manic episode looks like, and what to look out for but she completely misses the long us up that her daughter was on and doesn't notice until she's nearly killed? (hide spoiler)] 
 - INSTALOVE (view spoiler)[ I mean once we found out about Vivi's bi-polar I could understand her but what was Jonahs excuse? (hide spoiler)] 
 - The descriptions were a bit lacking, Vivi wears eccentric clothes but I could never imagine what she looked like properly. 
 - (view spoiler)[ Is it weird I wanted Jonah to be with Ellie? She was perfect and I loved her fellow girl respect she gave Vivi even when Vivi was an ass (hide spoiler)] 
 - Hated the romance 
 Likes: 
 - Deals with mental illness in a well done way 
 - I love large families in YA and this family was to cute 
 - I liked Jonah but felt he was am idiot "in love" sometimes 
 - I liked the characters separately 
 - Vivi's character was eccentric and fun and I enjoyed it BUT (view spoiler)[ I hated reading about the things she did when she was Manic it made me cringe and start to dislike her even though I new she wasn't 'herself' (hide spoiler)] 
 - The plot was quick and didn't drag
