It’s the funny side of homicide in acclaimed TV comedy writer and novelist Laura Levine’s newest mystery featuring Jaine Austen and her snarky cat, Prozac, as a ghostwriting project sends the Hollywood writer-for-hire on a luxury train trip with strange company, extra baggage, and murder . . .

What could be more idyllic than starting a new gig with an exclusive train ride from Los Angeles to Santa Barbara? Turns out, a whole lot. Jaine must figure out how to tolerate her client—Chip Miller, aka Iron Man, a wealthy gym chain owner—who Jaine soon discovers is a tyrant and a bully with an ego as pumped as his pecs.

Practically everyone on board seems to have it in for Chip—his dysfunctional family members, his beleaguered staff, even his supposed best buddy from the gym. So it’s no shocker when he’s found dead in his cabin. Unfortunately for Jaine, she’s the one who finds Chip’s body, leaving her DNA on the murder weapon, and making her a prime suspect in the police investigation.

Forced to save her own caboose, can Jaine chug on through an unexpected love connection and ID the killer—or has she finally reached the end of the line?
