I was completely taken with Leigh Bardugo's debut. Shadow and Bone is marvelous... seriously. The world is richly detailed, the main and secondary characters are engaging, and the fantasy elements distinctive. I couldn't put it down!Alina doesn't think she's anything special, until she accidentally taps into previously unrealized power within to save her best friend... power that marks her as Grisha. The Grisha are revered in Ravka and are much above Alina's current station in life. She is taken under the wing of the Darkling, the mysterious and powerful leader of the Grisha, and is forced to leave her best friend behind in order to train among her new found peers in a world she knows nothing about.The time Alina spends training with her fellow Grisha successfully allowed the reader to observe external and internal changes of the heroine and was a great opportunity to learn more about the culture and world of the Grisha. I love how much depth and detail is present in Shadow and Bone, as it is usually the aspect of YA Fantasy I find lacking.Bardugo doesn't make things easy for the reader. The reader and Alina are often unsure of who to trust, sharing the same insecurities. Except the reader doesn't have the weight of saving Ravka on their shoulders like the unsuspecting heroine...And there's romance! And two possible romantic interests! And no love triangle! How is this possible, you ask? I'm not telling... because that would be very spoilery. And who wants that!?Great YA fantasy doesn't come along every day... do not miss Shadow and Bone!
