I loved this book! I finished Nightshade in a single sitting despite the large 528 pages. Once you read the first chapter you will be hooked. 
 Young Adult books in this genre are becoming increasingly common but this is a truly standout addition. The NIGHTSHADE world is unique and detailed, with a cast of characters that bounce off the page. I'm a big fan of love triangles and the love triangle between Calla, Shay and Ren is brilliantly done with the author giving us different things to love about both Shay and Ren. I had a hard time choosing which character I would want Calla to be with and this made the story that much more engrossing. NIGHTSHADE has more sexually detailed themes than most young adult series but it's interwoven into the storyline so that it makes sense. 
 Andrea Cremer has excelled at writing a detailed history of the NIGHTSHADE world without giving it to the reader in large doses. The progressively given information is used to support the mysterious storyline as well as explaining aspects of Calla's connections to the other characters. 
 The story itself will have you guessing right up to the last page and desperately waiting for the next installment after reading the cliffhanger ending. You can't tell that this is Cremer's debut. It's better written than many successful authors. I can't recommend this book enough. 
 5/5
