It's not every day you read a book whose heroine is an apparently dull accountant. Perhaps Rosenwyn Tremain is a bit dull, but her life changes overnight when she finds herself driving to Cornwall to carry out an accountancy check on a pub. When she arrives at the pub, she meets twin brothers Michael and Niall O'Connor, and from that point on nothing is the same. She feels a strange connection to the reserved Niall, but he seems to be hiding something. Part of her reason for visiting Cornwall is to search for her father, a man she doesn't remember. There's more to him than she could possibly have imagined, though, and meeting him starts her on a quest, along with Niall, Michael and another unusual male, to rescue a whole race of piskies and help Niall keep his sister safe.
Rose is a good heroine, fairly down-to-earth and able to take dramatic events in stride but knowing that focusing on people is the most important thing. Niall, however, is an unsatisfactory hero, a bit too moody and reserved with a dreadful tendency to not tell Rose what's going on, leaving her constantly in the dark. The other characters, while well-described, don’t ring entirely true.
The setting first in Cornwall then Ireland is interesting enough, although our English/Irish protagonists slip incongruously into American language at times. Some dramatic plot events aren't always handled very well, and the central romance doesn't feel particularly romantic. However, the story is interesting and paced well, and the change in setting from Cornwall to Ireland is also good.
