The plots included a hearty helping of the fantastic, with Bond thwarting an Arctic weather machine in Storm Bringer. In Blackclaw's Doomsday Plot, 007 tangles with a mad SMERSH scientist who has an island lair and a laser that would be the envy of Dr. No and Scaramanga. For the record, the Bond Girls are named Yvete LaRue and Dr. Margaret Manfield.
The Play Value Books were licensed by both Danjaq and Glidrose and published by Grosset & Dunlap, a member of The Putnam Group, which was Bond U.S. publisher at that time. Maybe it was just a coincidence that these were released in the year that there was no official James Bond continuation novel from John Gardner.
The back of the Play Value books advertised a total of four James Bond storybooks. However, as far as I know, Operation Big Brain and Target: 007 were never released.
