Logic is the author’s enemy. Frustrating read, because there were some neat ideas in there. It’s a longer series and I shudder to think how bad the plotting and characters will get when built on a basis this shaky.
Plot summary
Beware: full spoilers! Also probably incomplete and possibly incomprehensible.
Sirius escapes when Harry is 7, takes a long time to get cleared, and logic is the author’s enemy, pacing is awful, the end.
