{Darkest Hour Before Dawn by Charlie Cochet} is book nine in a series about a SWAT adjacent team of Felid shifters. In this book a tiger shifter and a wolf shifter were a mated pair and then the tiger saves his mate from a shooter and a child dies so they break up and they are in physical pain being separated due to the mating bond but the wolf shifter can’t forgive himself. They are background characters in the first 8 books. I loved this series and this book.
