Challenge is a much better LitRPG than most. I have listened to or read many series in the genre. Some of the common traits among the least appealing ones are; emotionally weak MC, unwilling MC, unintelligent MC accompanied by much more intelligent secondary character to push him along. The MC does not share the aforementioned annoying traits. Thank you Edward Castle for giving us a strong, willing, and capable MC to follow and root for. If you love LitRPG, read or listen, then share this book with your friends. This book does not have nearly enough reviews and that tells me that more people need to enjoy it.
