The Last Oracle is Rollin’s fifth Sigma Force novel – after The Judas Strain, which spent 12 weeks on our fiction and mass market lists.  Publisher’s Weekly review said, “Lots of absorbing scientific information and tantalizing sentences like “With two rifles strapped to his back and a boy and a chimpanzee in tow, Monk marched down pitch-black tunnel’ keep the pages flying by.”  More pages will be flying soon, when Sigma Force #6, The Doomsday Key, is out June 23.
