I really wanted to like The Vault of Dreamers but unfortunately, I just had so many issues with it and had to push myself to care enough to finish it. 
 First, I needed more background about the story and the world itself. The story starts with Rosie Sinclair having already been at the Forge School for about a week or so. We're just kind of dropped into this story already with barely any lead up. There is a history given of the school but not until farther into the book. This story also takes place in the near future but again, it's not talked about until later. I couldn't even tell you what big catastrophe happened because that's how little I remember or care about it. 
 Second, the entire time I was reading I was constantly reminded about how young Rosie is. I was surprised when she mentioned she was 15. I couldn't get it out of my head how young she was and that reflected in a lot of her decisions and ended up annoying me greatly. For example, it should have been very obvious that in a school with advanced technology that the simple act of using someone's key card could be traced backed to them. She makes some dumb decisions and I really didn't want to deal with a young teenage girl in this story. 
 Third, I had zero interest in this romance. ZERO. It's so completely random. Linus shows up out of nowhere and all of a sudden they kiss and then he's an ally to Rosie and what?! They barely know each other but he has Rosie demonstrating just how young she is. No thanks, I'm not interested. 
 Lastly, the ending. I have no idea what happened. I'm not dying for the answer to this cliffhanger. I'm just confused. 
 The Vault of Dreamers could have been better but it fell flat for me. I considered dnf-ing it about half way through because I just didn't care. I wasn't hating it but nothing was enticing me to pick it up. I pushed through because the premise still had me intrigued but it still only ended being okay. I might pick up the sequel because I maybe want to find out what happened in that last scene but again, I'd have to push myself to care.
