Fire Of Love by Preston Walker

Old flames reignite.
Moody is an omega wolf, known for his sexy pouts and inability to get along with anyone.

Isaac is an alpha with a dark past, betrayed by his former pack and exiled from their number after being accused of arson. Now, old memories are coming back to haunt him.
Being together again comes with plenty of risks as they find themselves experiencing all their old feelings anew. But, before they can embrace a future together, they must uncover the true culprit behind all these fires.

When all is said and done, someone is going to get burned.
