In the Still of the Night — Callie Hutton

This book is 100% created by the author. No AI was used. It was supposed to be just another overnight shift at the zoo where Holly McCabe worked…until she discovered something more dangerous than lions and tigers lurked in the darkness. Holly McCabe works the overnight shift at the local zoo. She likes the peace and quiet but never forgets that the only thing separating her from the dangerous animals surrounding her is a fence, a moat, or a sheet of unbreakable glass. What Holly doesn't know is that on this night, a greater threat lurks in the darkness at the zoo. Someone who has revenge in mind. Someone who wants to kill her. But first, like the great cats on display at the zoo, he will play with her.
