Frost Bite by Marissa Dobson

After the murder of his parents, Frost splits his attention between raising his sister and making the world a safer place for her. When the chance to join the Shifter Peace Keepers arises, he can’t pass up the opportunity. He never expected his first mission to bring his mate into his life.
When the lone wolf shifter Alicia Huntington has worked for is murdered and a group of dangerous shifters are suddenly after her, she’s left with no choice but to contact the Alaskan Tigers for help. Being a human surrounded by shifters, Alicia never expected to find the family connection she’s longed for.
Frost and Alicia each have something the other is missing; they balance each other out, but they both come with baggage.
Can they let go of the past in order to accept what is in front of them?
