As ReganBooks' Witness claims its fourth week on bestseller charts, the HarperCollins imprint announces yet another release about Scott and Laci Peterson, this time around by Anne Bird, Scott's half-sister. According to the press release,

Bird, who was put up for adoption at birth, was reunited with her biological mother, Jackie Latham Peterson, and her brother, Scott, in 1997. In her book she reveals, in shocking and riveting detail, the untold story of Scott, Laci, and the Peterson family.

Assigned the ridiculously double-entendre title Blood Brother, and subtitled "33 Reasons My Brother, Scott Peterson, Is Guilty," the book hits bookstore March 1. As for ReganBook's marketing strategy, Senior Director of Publicity Paul Olsewski gave GC a stiff "No comment."

The bigger question, though, is whether Blood Brother will enjoy Witness's wild success (119,000 copies sold and counting). According to Slate, probably not; Frey "has become a stand-in for the case's real saint, Laci Peterson," the online mag theorizes. And such simplistic transference requires the matching simplicity of a love triangle, not the complexity of a family saga.
