Got several books going but none are from my core collection, that decade and a half frenzy of white hot book collecting where I bought way more than I could keep up with if I read constantly 24/7, and this is my attempt correct it by squeezing it between UNDAUNTED COURAGE and THE ADVENTURES OF CAPTAIN HATTERAS.
Kevin O'Donnell always impressed me when I came across a story of his when I was reading Analog on a regular basis in the late seventies. Picked up six or so of his novels as they came out but put them on hold for some reason I can no longer remember. Only a handful of pages into it but I like it and it feels promising.
