Angel in Spikes: The Werewolf Saga

When they reach Frank's beautiful home in the midst of the snow-covered hills, they meet his younger brother and accept their invitation to stay for the weekend with them.
The women quickly fall in love with the two utterly handsome werewolves, who turn them into their own kind overnight, which Angela and Sharon learn to appreciate--not just because of their feelings for the brothers, but due to the superhuman powers that they acquire through it.
