I received an e-copy of this book from the author for possible review.There were a lot of things I enjoyed about Radiant. Mary is a main character I hadn't seen before. Her mother's family is Vietnamese, and both Mary's mother and grandmother are a huge part of her life. I really enjoyed learning about these three generations of her family. Mary is also an artist with an interest in astronomy, and loves to look at the sky through a telescope on the roof of her building. She's seventeen, but her voice felt younger than that to me, more like a tween. She's not your typical snarky, rebellious teen. She's quite earnest, and struggles a little academically, but is obviously smart.Mary doesn't have a ton of friends at school. So when her popular classmate Carter not only saves her life, but starts following her around like a lost puppy, she's confused and curious. Carter's friends seem to write off his weird behavior as a result of his near-death experience, but Mary has a bunch of different theories about what might have happened to him and starts investigating. Post-accident, Carter comes off sort of like an even more robotic Sheldon from the Big Bang Theory.While I liked this part of the book, it did feel a little long -- we're kept in the dark for a long time about exactly what the deal with is new Carter and the tension begins to wane a bit. On the plus side, this new Carter and Mary began to seem like two quirky people who were perfect for each other.By the end of the book, all is revealed and a several other sub-plots and secondary characters-- Mary's missing father, the murder of a woman in the neighborhood, and a weird janitor -- are all neatly wrapped up. Though I felt that a lot of the action was loaded into the last few chapters, I thought that the author did an excellent job tying a bunch of seemingly disparate plot elements together in a way that made complete sense.To me, Radiant had a sweet -- if slightly young for YA -- voice and romance, a twist that kept me guessing, and a slight drag in the pacing that was redeemed by a well-crafted ending. If this sounds like something you'd enjoy, definitely give Radiant a try. Read more reviews on my blog, YA Romantics!
