Questions about print format

[timharvey]

Hello, I'm wondering about part 2 of the Sonic Boom trilogy. It comes in mass-market paperback. But parts 1 and 3 come in 5x8 inch paperbacks.

Where can I find part 2 in 5x8 inch format? Or did it default from the beginning to have a mass-market paperback format? Thank.

Part 2 was initially released as only a mass-market paperback, while parts 1 and 3 are in 5x8 inch format. No official 5x8 edition exists; please check with the publisher.
