“First, I think the story is excellent and is well worth reading. However, the mass market edition was actually published before the trade book edition — and it suffers from having a much lower level of editing that the later edition. (The physical book is also less attractive.) Since used copies of the trade book edition sell for about the same price as this edition, there’s little point in purchasing this version. Get the trade book edition — you’ll appreciate the story more.”–PETE IN THE BAY AREA
