This is a long read (516K words!), since it covers all Harry's years at Hogwarts up through Goblet of Fire, but worth it, though the ending is still only partial and a bit downbeat.
There's plenty of magical action and more than a little humor, but it also addresses some serious issues such as PTSD and prejudice.
I like how both adults and young characters are well-portrayed, and of course seeing logical deduction applied to the magical world makes for some interesting changes.
There are still-uncorrected typos and others errors, but not enough to impede enjoyment.
