Haven by Teresa Gabelman

Raised by shifter parents, Sadie has always straddled the line between two worlds. Now, on the run, she’s desperately searching for a sanctuary where her shifter sister, Lily, can be safe and embrace her true nature. Along their journey, they encounter three brothers, but it’s Kile who awakens something deep within Sadie.
Kile, a wolf shifter working with his brothers at Stone’s Wolf Sanctuary, steps in when he sees Sadie being harassed by a pack hunting her and Lily. As his feelings for her grow stronger, he becomes determined to protect her, urging her to stay at the sanctuary where she can find safety—and where he can claim her as his own.
Now, Sadie faces a choice: stay within the sanctuary’s haven or venture into the human world she’s been kept away from.
