This book was an enjoyable addition to the Whimbrel House series. The introduction of new characters and a new setting was a welcome change, as well as the focus on Owein as a character. The manor house and surrounding locations were well detailed, although the side characters were more one-dimensional. This did allow for more focus on Owein, Hulda, and Merritt, but I wished there had been more tension and rounding out of the suspects leading up to the reveal at the end. The introduction of the Druids was fascinating, and the world expansion was done very well overall. I will definitely read another book in this series if one is planned!
