"A top secret mission on behalf of an old friend, a tropical cruise. What could go wrong? Turns out it's a theme cruise -super-hero themed, naturally -a floating comic con. Now Bobbi is trapped on a boat with a thousand cosplayers, caped colleagues she was trying to avoid, an ex-boyfriend who keeps showing up at inopportune times and a rampaging herd of corgis. When a passenger is murdered, Bobbi must play Hercule Poirot to find the killer and confront some uncomfortable truths from her past in the process."--provided by Amazon.com.
