Andrew Hussie is the creator of MS Paint Adventures, a collection of webcomics that includes Homestuck, as well as of several other webcomics, books, and videos.
This very quickly lost all relationship it barely had to Harry Potter and became a thing of its own. It's a Hussie book. There's cultural references, cool time shenanigans, a very convoluted plot and narrative timeline, that one powerful but bipolar mage character, the surprise visit to a dilapidated Oval Office... A lot of familiar stuff! And it's fun and good, despite being an incomplete, abandoned work. Honestly, it was worth the read. Some more unappealing moments where everything is so incredibly random or I had forgotten who was who, but they were compensated for for sure. Kinda wish it had been finished.
Andrew Hussie has serious mental issues, and that becomes more apparent the more you read from him. What does any of this even mean. What have I read here. It just abruptly stops in the middle of a sentence because it was never finished or published. Where the hell is my skelephant.
