Books worth buying in stacks.
IF/THEN Books are interactive detective fiction. Real, full-length novels with branching paths built in. Designed for the kind of reader who finishes a chapter and immediately wants to go back and try the other choice. Below: how to order, what's available, and what we offer schools and libraries.
Where to order.
The full IF/THEN catalog ships through major school and library distributors as well as the standard retail channels. Order through whichever account you already use.

Branching narrative is built for re-engagement.
The IF/THEN format works for the same reader two different ways. The first read is forward motion: a kid who normally puts the book down at chapter three keeps going because the choice they made on page 40 already paid off on page 70. The second read is the rereading habit you actually want to cultivate. The text is the same; their experience of it isn't. Three paths through one book is three experiences of the same vocabulary, the same characters, the same craft.
Each title supports independent reading by confident readers in the 10–13 range, group reading where students vote on each choice, and read-aloud with younger siblings who want to be in charge of the decisions. Reading time runs 4 to 6 hours per path; most readers play through twice or three times.
The mystery and detection genre keeps the stakes earned. No violence beyond PG, no romance, no swearing. The hard moments come from clue-weighing and trust judgments, not chase-novel cheap thrills.
