I actually read this as an ebook just like the first one in the series, Switched. When I enjoyed the first one as much as I did, I went ahead and purchased the 2nd and 3rd as ebooks, I believe for only about $2.99 at the time. Like with the first one, I read this on my iPhone Nook app whenever I was somewhere and didn't have a book with me. After I finished my last book, I decided to go ahead and finish this book. These are now coming out in actual "books" so I thought I'd go ahead and get my reviews done on them. At the beginning of this Wendy has run away, back to her human family, to get away from having to be the Trylle princess. She just wants her normal life back, and believes she can actually do that if she leaves. She brings home Rhys, the child that she replaced as a changeling. So her human brother Matt gets to meet his "read" brother. But of course, she can't just go home, as it turns out there are other trolls out there, the Vittra, who come back to try to kidnap her, and do succeed. They take her to their king, who turns out to be her father. But while she is being held there, she learns about why the Vittra want her, and meets her stepmother. She learns the Vittra can't have children, and hope that she can come in and help them, as she is a mix between them and the Trylle. Finn comes in as a Tracker to rescue her, along with her brothers Matt and Rhys. They all are taken back to be safe in her mother Elora's home. Wendy learns that she must become the princess in order to save her people, and must even become betrothed to help. But there are some mysteries she must solve while she's there, like why did it end up being so easy to escape the Vittra, it was like one of them just let her walk out, a Markis named Lucas. And why then does he show up at her mother's home? I enjoyed this book, and will probably read the 3rd one in the next month or two. I look forward to seeing how it will end. As I mentioned in my review of the first one, I'm glad we still don't really have a love triangle, at least not to the point of other stories these days.
