Do you want something sugary?  Do you want something sweet? Do you want to constantly be grinning at your screen like a fool, feeling purified and at peace with the world?
Honestly the tragic backstories, this is the kind of book that can put you in a complete sugar coma and manages to do it entirely without miscommunication.  It's pretty standard in tropes and framework but the relationship is so good and so strong pretty much from the start that you keep coming back for more.  Just a really good, really sweet novel.  I'm stuffed full of diamond dog food.
