The Mountains Wild by Sarah Stewart Taylor

Maggie D'arcy has a successful career as a cop on Long Island. But when she receives a call from her Uncle Danny to tell her that the police in Dublin have found a scarf that they believe was her cousin Erin's, Maggie is transported back to twenty-three years ago when Erin disappeared. Maggie and Erin were very close growing up, and when Erin went missing, twenty-two year old Maggie travelled to Ireland to try and help find Erin, to no avail. With this latest development in Erin's case, Maggie again goes to Ireland, now with professional expertise, hoping to finally bring closure to her family. The Mountains Wild tells the story of Maggie's journey with the two storylines in 1993 and 2016. An engaging yet leisurely paced start to the Maggie D'Arcy mystery series.
