Holmberg rarely disappoints and hasn’t in this sequel to Keeper of Enchanted Rooms. Hulda and Merritt must deal with her missing director at BIKER, the investigation by LIKER, the London equivalent of the Boston agency, into missing funds, and another magic-user putting obstacles in their path. Owein, the ghost who used to inhabit the walls of Whimbrel House and now living in the body of a dog, is as always delightful as they try to teach him letters so he can spell out messages to them. Others from the first Whimbrel House story are also on hand, including Baptiste. Meanwhile, Merritt must grapple with his family, who he hasn’t seen in many years. The developing romance between Hulda and Merritt enriches the historical fantasy.
