Fast paced, thrilling ride and action packed.
Thoroughly enjoyed this read, definitely easy to read within a day, just set aside those responsibilities, they will be there when you finish this book!

It is book 4 in the series, however, this was the first one I read and didn't feel like I missed any critical info from the previous 3 books.

An explosive prequel to the L’Inconnu series, Unchecked: Renegade Force takes readers deep into the chaos of a maniacal bomber targeting police. The tension is high, the pace is relentless, and the stakes are wildly intense.

It’s a thrill to watch Remy evolve into the detective we’ve come to admire in later books. And a special shoutout to Marmalade the cat, the unsung hero who, may or may not, actually save the day.

Dan Grylles proves once again why he's one of my absolute favorite authors. If you love:
