Griffin by Ally Summers

For Officer James Griffin, little sisters are off limits.
Officer Griffin, bear shifter, has been looking for love, in all the wrong places. He wants to settle down with a mate, but so far, no luck. Instead, he’s decided to throw himself into his work and catch the people responsible for Casey Green’s disappearance. But when Casey’s sister Liz shows up, everything changes.
Elizabeth Green has a fancy job in the big city, one that is slowly sucking the life out of her. But as a lawyer, she loves helping people, and sometimes that includes her dumb big brother. She goes to Hunter’s Lake to look for him but instead comes face to face with Griffin. He’s handsome and kind but she’s leaving in just a few days. Even if her tiger can’t get enough.
The two must solve Casey’s case together, in order to give their hearts a chance at one true love.
The small town of Hunter’s Lake has always been a refuge for shifters, until now. The Undercover Shifter unit must fight against the clock to save the town they love, and the people in it.
