You Owe Me a Murder

Seventeen-year-old Kim gets more than she bargained for when she is set up for murder.
Kim never expected to plot a murder. But that was before her boyfriend dumped her for another girl. Now, Kim’s stuck on a class trip to London with him and his new soulmate and she can’t help wishing he was a little bit dead, even if she’d never really do that.
But when Kim meets Nicki, a stranger on the plane who’s more than willing to listen to Kim’s woes, things start to look up. Nicki’s got a great sense of humor, and when she jokes about swapping murders, Kim plays along—that is, until Kim’s ex-boyfriend mysteriously dies.

Blackmailed by Nicki to fulfill her end of the deal, Kim will have to commit a murder or take the fall for one.
