Melanie Joan Hall is a best-selling author in a bind. Her publisher needs her to tour on behalf of her newest blockbuster, and Melanie Joan needs a bodyguard-cum-escort to protect her from an overbearing ex-husband whose presence unnerves her to the point of hysteria. Sunny's cool demeanour, cop background, and P.I. smarts are an instant balm for the older woman. She begins to sense that Melanie Joan's ex - a psychotherapist - is not your basic stalker, and when an incident at a book signing leaves the ex-husband bloodied and the author unconscious, it's clear the stakes are high.

Deciding that the only way to crack the case is from the inside, Sunny enters therapy herself, only to discover some disturbing truths about herself . . . while putting her life on the line.
