If you are a fan of Supernatural and love young adult paranormal fiction then you should definitely check out Sisters of Blood and Spirit by Kady Cross. It follows twin sisters Wren and Lark Noble, the catch being that Wren was stillborn while Lark is alive. This doesn't stop them from being best friends, even though talking to the dead has landed Lark in the psych ward after attempting suicide and a solid reputation as the crazy girl in town. Despite what sounds like a heavy premise, this story is basically a fun paranormal adventure ghost story. A lot of the ghost and spirit lore is recognisable as that which also appears in the Supernatural television series (not that Supernatural has the monopoly over this particular lore) and the sisters are essentially kick-ass teenage Hunters. 
 I thought that the overall premise was fairly unique, with each main character being torn between being not fully alive and not fully dead because they are bound so tightly to each other. The ramifications of this bond create a lot of complications for the sisters, but also make them uniquely suited to helping a group of Lark's schoolmates who run afoul of a band of particularly malevolent spirits. The overall plot is interesting and well written with the right amount of tension and suspense to keep you engaged. I really liked Lark, she was snarky, smart and interesting and there is a dash of romance if that is your thing as well (although I enjoyed the fact that a lot of the focus was placed on the bond between the sisters, rather than simply romantic pursuits). 
 So, overall, the story is fast paced and the main characters are engaging. There are funny parts and the tension is built well towards the conclusion. I thought the bond between the sisters was quite beautiful and well done with the use of the dual point of view. I also enjoyed the paranormal lore. My only real complaint is that certain aspects of the world building were underdeveloped and a lot of questions were left unanswered, which was a little bit frustrating. It felt like there could have been a lot more detail to the world that was created, but instead we were left in the dark. Ultimately it was the world building that I enjoyed the most about this story, so that fact that it was underdeveloped in parts was a real let down.
