The Halfblood Wizard: Perseus Jackson. ~~~ Previously Titled Halfblood at Hogwarts New Title by HorcruxDemigods7 Cover by Inheritance21 ~~~ "You know when you find a bunch of 'okay' books on Wattpad but every once in a while you find one that you just have to stay up 'til the sunrise to finish? This was the book to make me stay. Percy's persona is wonderfully written, the grammar is perfect, and it is completely original. Well done and I can't wait to read the rest." ~Unrealqueen "DAM YOU ARE THE GODDESS OF WRITING" ~Labinzel "This is one of the best stories on Wattpad period. Not just in fanfiction or crossovers but out of all the books on Wattpad. This is THE BEST and my FAVORITE. You are such a good writer!!" ~fanficreader14 ~~~
