Courier contemporary noir psychological thriller
A JOURNEY THAT BREAKS THE RULES

The road challenges everything Lion believes about survival. Each turn forces him to abandon familiar methods and rely on a stranger who doesn’t speak.

Every answer reveals a larger question. The destination matters—but understanding why the journey happened matters even more.

The threats are obvious. Trust is not. Sometimes opening up to another person requires more courage than facing danger.

READER FEEDBACK

A gripping and well-paced thriller that kept my attention from the very first chapter all the way to the end. It is hard to believe this is the author’s debut. The story is engaging, the suspense builds nicely, and the ending is satisfying. A very strong first book, and I am definitely looking forward to reading more from this author in the future.

I really enjoyed this book. It’s an easy, smooth read, but it keeps you interested the whole time, and the ending definitely caught me off guard.
If you’re kind of over true-crime or romance books, this is a nice change. It’s about two young guys who get thrown into some pretty tough situations and have to figure out how to trust each other.
This is just the first book in the trilogy, and now I’m impatiently waiting for the next one.

I read this while flying from Halifax to Thunder Bay, and honestly the time flew by. This book kept me hooked, and I couldn’t stop until I got to the end. It’s an easy read, the pacing is good, and the ending surprised me.
Solid first book in the Onyx Effect series. Going to buy the second one!
