MIA: A Title For My Next Novel

I’m working on the sixth draft of my current Casey Holland mystery. The book’s coming along nicely, except that I haven’t yet found the right title. Titles used to come easily for me, but for some reason the more books I write, the harder it gets.

The sixth installment in the series has Casey’s employer, Mainland Public Transport, (Casey’s a female security officer) under siege by an arsonist. Two of the company’s bus drivers have also been attacked by an unknown assailant who’s been attacking others in the same area of Coquitlam BC. Meanwhile, local thugs hold a grudge after an ugly confrontation with Casey and a driver during a riot. This isn’t the book blurb,  just my thoughts about will eventually be a blurb.

One of the ongoing themes is anger, the way it permeates the workplace, the public, and one’s personal life. Another part has to deal with mental illness issues that drivers in real life face from the public nearly every day.

There’s a lot of action and drama, which should make finding a title easier, yes? I’ve been compiling a list of key words and trying mind mapping, but so far nothing’s working. The title, Under Siege, aptly describes the plot and subplot, but it’s been used in movies and books many times before. So, if anyone has some great tips on coming up with a title, please let me know!
