Books for children by Mary Arrigan

A Hollow In The Hills by Ruth Frances Long  (O Brien, €9.99) 

The second story in this trilogy is again set in two versions of Dublin, one the city of the present day, and the other, Dubh Linn, a city peopled by faes, angels and demons.

The heroine, Izzy, now knows that she, like her father, is a Grigori, one who must mediate in what is becoming a terrifying pitched battle between forces she barely understands.
