The awakening / Nora Roberts.

Breen Kelly had always been a rule follower. So, when her father left when she was twelve years old, promising to return, she waited. Now, more than a decade later, she's working at a job she hates and is tired of the life that playing by the rules has dealt her. It's time to make a change. Breen makes a leap into the unknown with a summer trip to Ireland - her father's homeland. Little does she know how much of a leap until a walk in the woods leads her through a portal into another world - Talamh - where Breen will find magic, family and a destiny she could never have dreamed of.
