Description
Adventure | Mystery | Faith | Courage
The Jillian Dangerous duology follows the unforgettable journey of Jillian Cassidy—an intelligent, strong-willed girl who refuses to let fear, doubt, or even time itself define her.
When unexpected twists transport Jillian and her friends into thrilling and sometimes dangerous situations—including a mysterious boarding school and a time-bending adventure into the past—she must confront bullies, secrets, wild jungles, impossible choices, and her own inner struggles. Along the way, Jillian learns that true courage isn’t about being fearless—it’s about trusting God, standing firm in your identity, and choosing bravery even when you feel small.
Filled with suspense, heart, humor, and powerful spiritual themes, Jillian Dangerous inspires middle-grade readers to:
- Stand strong in who they are
- Face fear with faith
- Build loyal friendships
- Discover purpose in unexpected places
- Trust that God is at work—even in the unknown
Perfect for readers who love meaningful adventure stories with depth, danger, and a message that lasts long after the final page.
Also available as eBooks.

HELLO! I really enjoyed reading these books! I like how Jillian’s (main character) life was tied in with her relationship with God. It worked very nicely. As a young believer myself it helped me understand God better. I could not put the book(s) down and I wanted to keep reading. These books made me feel closer to God as well as have a better relationship with him. I also liked the time travel and mystery elements. These books also have really cool covers. Overall I totally recommend these books! They’re SOOO AMAZING!!

This is Alina and I am 8 years old and in third grade.So I just finished this book. And I like it mostly because it is a mix of so many different things: fantasy, history, time travel, adventures! Even a spooky, off-limits mansion! And a very brave girl: Jillian Noel Cassidy. I really enjoyed reading it and I spent hours a day reading it! I definitely give it a five star review!

The book is well written and full of adventure and suspense. Adolescents and teens would find it quite readable and relevant to the challenges and emotions they face. The element of time travel adds an interesting appeal to the imagination.
