I’ve been hearing from some sources that Canadian chain store Chapter/Indigo isn’t currently stocking Something Secret This Way Comes in paperback. I’ve brought this to their attention, but please feel free to request the book from them directly, as the more requests they get the more likely they are to make an effort to stock it in the future.
In the meantime, if you’re craving a paperback copy of Something Secret, check out these sources as an alternative.
Check with your local independant book stores as well. In the US the book in available through Amazon, Barnes and Noble, Books-a-million and most other chain stores.
