I loved the story of The Lighthouse Keeper. It was fun, and just the right amount of light-hearted to suspenseful for a summer read. Dawn's character was an interesting one. An odd mix of old-fashioned and modern-day. Her search for a place to call home was always present, but not so much that I felt like I was getting hit over the head with it.
Her treasure-hunter parents were quite hilarious. I loved their conversations, and you could tell they were two people that were completely comfortable with themselves and around each other. But I wondered throughout the book why they hadn't put more effort into finding the missing silver pieces. Dawn's father feeds her information every now and then throughout her search, and I had to ask myself, why didn't he follow up on that? Why wait until now?
The mystery of the missing silver was a really good one. And it did keep me guessing up until near the end, but the author was also very careful not to give away any clues ahead of time.
However, I highly recommend you read this instead of listen to it. The narrator sounded a little too much like the computerized voice you hear on automated systems for me. There wasn't a whole lot of emotion or inflection (until she had to do a man's voice, and that was just overdone). I might continue on in the series. I have no idea what the next book might be about, but I'll definitely read it instead of listen this time.
