Penny of the Paranormal: Shifter Romance (Vanguard Elite #4)

Three days to reach the summit and retrieve the flag.
Those who drop out go home.
The bootcamp’s alpha asks Allistaire to protect their omega wolf, Penny.
All they have are the clothes on their back when the worst storm of the winter hits.
But it's got nothing on Penny.
No shifter has ever torn Allistaire open or exposed him like her, all with the razor edge of her tongue.
Forget the blizzard, the real danger is the sharp curve of her smile and the lengths he'll go to get a taste.
