It's a modern day world where people born after "the Shift" can see and talk to ghosts, whether they want to or not. Most of the ghosts are just trying to finish their unfinished business so they can pass on, and many people have taken to helping them, the government even has an agency that keeps them in check, in case they go bad (turn "Shade"). They've even developed ways to keep them away from places by "blackboxing" areas like schools, malls, houses, etc. with Obsidian, which is a material that can ward off ghosts. 
 The main character is Aura, who you learn is the first person born after "the Shift". She's basically a normal teen who doesn't really care for seeing ghosts, that ends up losing her boyfriend to an unfortunate event. Logan was a hard character for me to figure out whether I liked him or not. He's not complex or anything, it's just sometimes he can be really sweet, and he truly does care for and love Aura, but other times he is quite the drama queen and hothead, I was honestly waiting for him to turn Shade at any minute. 
 Zachary is the new guy, one that Aura is instantly drawn to, despite her love for Logan. You slowly see their connection and I do have a soft spot for him, typical nice guy. He also has something very special about him that will play a key part in the story. 
 Overall, it was a good book, certainly different from what's out there nowadays. Most of this book, the first in a trilogy, deals with Logan's death, how Aura and his friends and family cope with the loss, and their working together to help him move on. It wasn't totally captivating, but a good start to an interesting trilogy. I'm eager to see where exactly Smith-Ready is going with this.
