This book is certainly something which will make you grateful for what you have. Reading about Callum and Harper's struggles and how things just didn't go their way time after time really gets you thinking about all the things you take for granted everyday. So many people have had to go through what Callum and Harper did and it broke them, those experiences warped their personalities into something cruel, bitter, and unrecognizable. And albeit not everyone has had dealings with a serial killer in the making who then comes after you and girls who have similar characteristics almost a decade later, the obstacles Callum and Harper had to face were tough and everyone's worst nightmare. Sure quite a few people have probably lost some money to a thief, but they probably weren't relying on that money to buy a house which would keep them off the streets. And I'm sure there are a lot people who have had bad experiences with the law but I doubt many have almost been killed because of it. 
 For most of the novel anyone who is even slightly invested in it will be yelling 'you two are idiots! You love each other but since neither of you can pull on your adult pants both of you think you're in a fake relationship!'. 
 Callum & Harper was a beautiful read and one I will not soon forget (view spoiler)[though reading a book where two people in love marry for all the wrong reasons is quite memorable (hide spoiler)].
