Query: Bought this for a niece

Before I start, if you've noticed that many of my novels are 4s and 5s, it's because we read books from the library and then buy a few ofthem for gifts--there are plenty we don't like or don't rank as well. Most of the time, my kids have a say in any bought for their cousins.This is the first in a fun mystery series, and the child I have who read this liked this as well. The whole idea of Sherlock Holmes having a younger sister who ends up on her own working as a detective is appealing, and there is plenty of danger and adventure for Enola Holmes.
