I ignored people telling me to read this for WAY too long! So don’t make the same mistake I did! Pick this up immediately! In Greg’s Chicago, there is an underground world filled with Dwarfs and Elves! But Greg doesn’t know that. All he knows is that he has one best friend and a dad who is always off looking for weird natural remedies and teas. But all of that changes when his dad is abducted by a… troll?! This book is a crazy fun adventure filled with a fully thought out magical world set under my very own feet. As well as being fun and entertaining, it’s also a great story of acceptance of all people, regardless of race (even if those races are magical in this book). Greg is a powerful underdog and I wish that I had him around as a role model when I was growing up.
