This was a good one, which I doubted would be after I saw the very Hallmarky movie version, but then was reminded why I shouldn't have doubted it when I remembered that Angela Hunt is just a good writer. The story is sentimental and something that you can make cheesy, but the book is compelling and the writing style has a subtly to it that draws out the profound simplicity of what's going on.
The main character is flawed yet smart, and I enjoyed seeing the perspective glimpses of those around her as we move throughout the story. Her unraveling backstory is done pretty well, and the conclusion feels right.
My one qualm is a small moment that is maybe too vague for me to be bothered by... but according to the note-writer's daughter, she and her parents had a fight because she was interested in finding out about her birth mom, and her parents interpreted that as her somehow being ungrateful for her adoptive mom, and so they fought about it. Then in the note, he doesn't say "I'm sorry", he says "all is forgiven". Which is a good message, and I'm sure it's because they said things in the fight that were mean and harsh and he wanted her to know that didn't matter. But an adopted child has every right to want to find out about her birth parents, and it makes me uncomfortable that the parents interpreted that as ungratefulness and then didn't apologize for it, as if she was the true one at fault. I would've felt better if the note had said "I'm sorry" as well, or if the argument had been all on her. Obviously we don't know exactly what happened, but it doesn't sit super well with me.
But aside from that, I liked Peyton and the way she handled things, and so her story and conclusion was a good one.
