OK, so I give up on this one. The first book in the series was borderline, but my suspicions were bourne out in the second installment...
This is the continuation of the story begun in Angels Watching Over Me and picks up six months after Leah's stay (and recovery). Longing for her Amish friends (and her love Ethan in particular), Leah spends the summer in Napannee IN, near where the family lives. She learns a lot more about the Amish and has a few adventures. A dramatic tear jerker ending that comes out of nowhere will elicit a sob or more.
The writing style grows more stilted in this book, with such amzingly bad prose as "the rose fingers of dawn" and some amzingly bad dialog. McDaniel gets her style from adult romance novels and this is basically one of those, with a slightly younger heroine. The man is a wooden figure, his stoic boring nature explained away as being Amish. Leah's swooning, recounted repeatedly through the book, never quite seems justified or real.
The book came on a recommendation from a young reader, and maybe if you hadn't read a lot of romance novels yet, this would be appealing, but the story has little to do with growing up or learning to become an adult (like a decent YA novel) or with young people coping with disease (as the author claims her goal is).
