CIVIL WAR II TIE-IN!

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.
