Time to Kill

This is an Apple Books audiobook narrated by a digital voice based on a human narrator.

US Marshal Jordan Burke is happy for her partner when he takes a month off for paternity leave, but she's not happy about her substitute partner.  Nick Pierce worked for the Topeka Witsec office years ago and left under less than the best of circumstances. When he's asked to fill in he hesitates, but curiosity about Jordan makes him accept the job. The minute he sees her again he doesn't regret his decision. From Atlanta to Los Angeles, Jordan and Nick discover that danger, and help, can come from the strangest sources. While they struggle to protect their witnesses, the bigger challenge seems to be keeping each other alive. And there's always the possibility that they might kill each other first.
