This was a very fun young adult mystery. It was reminiscent of the Nancy Drew novels I grew up reading. I loved how Ms. Cross addresses the issue of bullying in this novel. Skylar learns to face her fears and stand up for herself through some strange circumstances but in the end she is a much stronger young girl because of it.There are a lot of aspects in this book that address issues other young readers could be facing such as going to a new school, meeting new and differently abled people, and being away from your parents for a summer. Skylar uses the skills she learned from her grandfather to solve a mystery involving the strange noises coming from the hills behind her Aunt Caroline’s Malibu home.This was a fun and interesting book and is the beginning of the Skylar Robbins Detective Agency series. It looks like there is another young female detective joining the ranks of the infamous Nancy Drew.
