Trick Or Treaty. The Morrigan Tales, #1

When your husband is a government spy and carries the legendary Sword of St. Michael, your great grandmother is the Celtic goddess of war and destruction, and your brother the priest battles Fomoriandemons in his spare time, life can get a bit rocky, especially when morning sickness is your constant companion.

Up until recently, Maureen and Fr. Kevin had always measured their lives against the yardstick of human normalcy. But it seemed that The Morrigan never asked permission. She said what she meant and took what she wanted, and it now appeared she wanted the three of them. And when the Queen of the Fae Otherworld demands your presence at her Samhain celebration, the endearing Halloween holiday suddenly becomes more trick than treat.
