Holly Edwards' teen novels are so popular that her publisher has commissioned her to write an adult book for the Famous Foremothers series. Holly tries to write about her great aunt who was a madam in Alaska but soon realizes that all she knows about Myrta Jane Wonders are some old family stories. She employs a Ouija board to summon the long dead madam, who proceeds to set her niece straight about the afterlife before helping with the book. Myrta returns with her ex husband, reputedly a gangster, and two women who allegedly worked at Myrta's House of Wonders. Problems arise when these visitors do not conform to Holly's expectations. House of Wonders provides a hilarious look at the evolution of family stories and a unique, uplifting view of the next life.
