Megan Messinger

Megan Messinger's sole credit in this catalogue is as one of five additional contributors, alongside Julie Holderman and Timothy Liebe among others, listed on Tortall: A Spy's Guide (2017), an in-world nonfiction companion to Tamora Pierce's Tortall novels, presented as the private files of the series' spymaster character. The publisher did not specify how the contributions were divided among the credited names, so it isn't possible to say which parts of the book are hers specifically.

A genuine search did not turn up an independent public author profile, other book credits, or biographical details for a Megan Messinger connected to this book -- no publisher bio, interviews, or prior/subsequent bibliography could be confirmed. Given the nature of A Spy's Guide as a heavily designed reference volume, it is plausible she worked on it in an editorial or packaging capacity rather than as a career novelist, but that could not be verified either way.
