Kristi McManus may be a pen name or less well-known author, as there isn't a widely recognized author by that exact name as of my last update in 2023. However, there is a popular author with a similar name, Kristin McManus, who might be the one you are referring to. It's possible that Kirsten McManus, another author with a similar name, could also be the one you're asking about. If you are looking for Kristin McManus, there is Kristin Cast, who sometimes writes under the name Kristin McManus, co-authoring the "House of Night" series with her mother P.C. Cast. If these names do not match the author you have in mind, it's possible that Kristi McManus is an emerging author or writes under a different name, and more specific information or context might be needed to accurately provide a description. If you have any additional details, please feel free to share, and I'll do my best to assist you.
