Happy birthday, Max Lagno!
Adam Online is a great but sadly underrated series. It's amazingly written, it has the most perfect story structure and engaging characters. The story feels different, unlike most LitRPG books, it has its own unique flavor and if that is what you're looking for in a book, we strongly suggest you give it a try. Perhaps you become a fan just as we did after reading it! Keep up the great work, Max!
