Need a Potter replacement!

So my daughter loves Harry Potter, all things Harry Potter. She seriously tried get everyone to call her Ginny as a nickname, never did stick! Lol She is older now, 13 (almost 13). She tackled the Potter books at 8 and just sped right through them. She has reread them over and over. She wants something similar. She has tried Percy Jackson, she loved them too, but not as much. She hasn't ready all of Riordan'so other series, my mind is drawing a blank on the name. She has the last couple on their way, but they aren't to arrive for about another week. She has Narnia books, and a few other. What she loves about the Potter books is all of the unique world that it has. The castle descriptions are fun, the wizard towns are great. Is there anything like it to be found? Any recommendations?
