I became immediately engrossed in What She Knew by Gilly Macmillan. A mother goes for a walk with her son and he runs ahead of her to go to the rope swing and disappears without a trace. Every mom’s nightmare, right?! While this was an enjoyable and enthralling story, it was too long. Also, the title didn’t make much sense to me once I finished the story. I am not sure who the she is who is referred to. But, on the whole, this was a good read. It certainly would be a nice one to pick up for the beach.
