Out Of The Box books in order

Reading order

The Out of the Box series by Robert J. Crane is a 42-book urban fantasy action series that continues the story of Sienna Nealon from the earlier Girl in the Box series. Sienna is a metahuman with multiple absorbed powers, and the books follow her as she faces increasingly dangerous threats in a world where people with abilities are both feared and controlled.

Crane published the series rapidly between 2014 and 2021, with several books released each year. The pace of the storytelling matches the pace of publication, with action-heavy plots that move quickly. Later entries in the series include titles that have not yet received publication dates, suggesting the story may continue beyond its current run.

With 42 entries, Out of the Box is one of the longer urban fantasy series in independent publishing. Readers who enjoy superhero-style action in a modern setting and are willing to commit to a long series will find plenty of material here. The books pick up directly from Girl in the Box, so starting with that series first is recommended.
