Bought it last night, went over it today. About 30 pages long, growth content starts on page 9. As the store says, it's vore-heavy. REALLY vore-heavy -- this is technically a food-based growth sequence, but taken to humorous extremes. A single bite of noodles makes Bonnie 10 inches taller, for instance. It carries on like that. Growth reaches somewhere between city and mountain range levels.
Word of warning, however: this is obviously only half the story, ending abruptly and without any big full-body comparison shots at her maximum size for the issue.
Sheela is a really great artist, so it looks pretty damned top-notch all the way through. Pricy, but highly recommended.
