Angelstruck: The Moon and the Stars #4 (Werewolf Shifter Romance) - The Moon and the Stars, #4

Lilly and her hairy friends are in for an equally hairy adventure when they're invited to a Midnight Party put on by a pair of well-connected movie moguls. Paul and she attend the gala, but the night is ruined when illness strikes. Worse, so does the werewolf and before they reach home Lilly has her hands full with trouble. Lilly doesn't get a time to breath between problems when an unusual visitor comes calling in search of Paul's aid.
The visitor doesn't take to the word 'no' and proceeds to attack the house. When the dust settles the parties learn that they're on the same side against a darkness known as Sin, a shadow formed by the unclean souls of unburied bodies. When Lilly and the others try to find the source of the Sin their search leads them to a horrible truth. Now they have to contend with several new foes, and all without Paul by her side.
Will they discover the truth in time, or will they all be swallowed by Sin?
