After a stressful foray into crime fighting, Hazel Dean is relieved to resume normality, taking care of her family and book shop–until her ability to see emotions in color pulls her into another crisis.

One night at book club, Hazel sees a swirl of jarring purple, blue and black encompass a young mother. Realizing that the woman might be in trouble, Hazel recommends a book that she hopes will provide some comfort and guidance.

To her horror, the young mother goes missing the following week. Hazel feels responsible and becomes obsessed with finding her. But the search isn’t the only thing Hazel is juggling. She’s also trying to help the missing woman’s children, evade a young reporter, and deal with the sudden reappearance of an old high school flame.

With all of Hazel’s efforts, can the missing woman be found before it’s too late?
