The bad news is that this is the last book in what is a very, very well written cozy series. There aren't enough good cozy series left out there and the loss of one is disappointing.
The good news is that this was the author's decision and as such, this book is written with no loose ends and for that I am thankful. It's bad enough to lose a good series, but for it to end abruptly, with stories half-told, is an insult on top of injury.
Hyzy doesn't own the copyright on this series or the characters, so while the story brings us to a good place for a series end, it's also left in an interesting place that allows for someone (Hyzy, one hopes, after obtaining copyright on what is arguably her own work) to someday bring Ollie and Gav back into the thick of things where they belong.
The plot is action packed, fast paced - almost a cozy thriller. It's got a bit of an out-there plot like a thriller too, but it works within the confines of the world Hyzy has created from the first. This isn't really a mystery at all; we always know who the perpetrators are and what they want; it's just a matter of what the solution will ultimately cost our MC. The final part of the roller coaster plot was gripping and left me with a bit of an adrenaline rush.
Thank you, Julie Hyzy, for 9 wonderful adventures with Ollie. I'm gonna miss her and Gav, although I'll revisit them often in my re-reads.
