Short Forms

This category is for books that are shorter than standard, typically being around four to six chapters long. Short forms are unique self-contained stories rather than side books for longer existing titles; such side books, as well as any title released to celebrate a holiday, is considered a special and belongs in that category instead.

Note: Per PB's FAQ, short forms do not count towards the app's "finish a book" challenge and will not give the usual 15-diamond reward for completing them.
