Kristen Conrad’s This is Devin Jones, published 2016, has many parallels with Die Hard, the plot centering on a hostage scenario where an out-of-jurisdiction cop must take out the bad guys and save the day. There’s even an exploding rooftop.
Here, however, the setting is a Hollywood awards ceremony and the hostages are world-famous actors, one of whom is the drop dead gorgeous ex of our hero – our hero being a super-hot cop in designer dress and heels, as capable with her gun as with her kick-ass self-defence.
Which is all perhaps a little clichéd and derivative, but it’s also good fun and there’s a dash of lesbian romance to sweeten it.
The need to change and make up names is a little distracting, and there are one or two minor continuity errors. Also, it’s a little too easy in the end; Bruce Willis had to run barefoot across glass, after all.
