Ronan Boyle has just discovered that leprechauns do indeed exist and they are not very nice. After his parents are wrongly put in jail, Ronan Boyle joins the Irish Garda, a police force tasked with keeping the magical creatures in line with the humans. While on the Garda, Ronan also tries to get evidence to prove his parents are innocent. This book was okay. I wouldn't recommend it for younger grades because I think it mentions drinking too much, and some of the Irish words weren't translated so it made it a little hard to read. Besides that, the book felt fun and magical and I liked the twist on mythical creatures a lot better than any of the other books I have read.
