Airman Polar Bear - Polar Bears of the Air Force, #3

Brent hasn't been this stressed since basic training. While he usually loves his position in the U. S. Air Force, having his leave canceled at the last minute has put a damper on his mood. When his roommate's little shifter sister whirls into his life, Brent has to act. Mary is hiding something and Brent has a feeling she's going to need his help. Mary is a polar bear shifter with nothing left to lose.
When her boyfriend finally loses his cool and hits her, she leaves town and runs to the one person she can trust: her brother, Ryan. When she shows up, she's caught off guard by the much-too-sexy male who lives in Ryan's spare room. But there's more to Brent than meets the eye. And Mary isn't the type of girl to shy away from an adventure.
