But for The Unbecoming of Mara Dyer, by Michelle Hodkin, the publisher got it exactly right: The book jacket art is not only eerie and interesting, but it reflects an actual scene in the book; and the jacket copy says just enough to get you to read it:
Mara Dyer doesn't think life can get any stranger than waking up in a hospital with no memory of how she got there. It can. She believes there must be more to the accident she can't remember that killed her friends and left her mysteriously unharmed. There is. She doesn't believe that after everything she's been through, she can fall in love. She's wrong.I enjoy this teaser so much that I'm not going to say anything more about the book, except that there are paranormal elements, the characters and situations are interesting and well-developed, there's some snarky humor, and if you like weird stuff, mysteries, and romance, you should read it! (There's also a sequel, on order and coming soon.) Ages 15 and up.
