Alan Dean Foster's 1976 Star Trek Log Six contains 3 stories adapted by Foster from the screenplays of the early 1970s animated cartoon television series that had been spun off from the original acted series of half a dozen years earlier.
Never having seen the animated series, I can make no comparison between the original episodes and Foster's adaptations, in the way I occasionally have with James Blish's adaptations of the original series. I can comment, though, that the cartoon series evinces some differences from the acted series. Here, for example, we have a handy piece of technology called a "life-support belt," which creates a very thin but tough force field, meaning that characters can stomp around in vacuum or poisonous atmospheres as if in a spacesuit. And of course another product of the animated nature of the show is that we have a few alien crew members--three-legged and three-armed, cat-like, or winged, for example--who would have been too expensive to produce every week via elaborate costuming, along with other odd aliens occasionally encountered. These differences are commonsensical, at least in science fiction, and they do not draw attention to themselves unduly.
In "Albatross," whose original script was by Dario Finelli, the Enterprise is on a seemingly "long, dull mission to Draymia" (1977 Del Rey paperback, page 5), a world potentially looking for "expanding trade and cooperation" with the Federation (page 12). But "[f]ollowing successful delivery of medical equipment and supplies" (page 10), Dr. McCoy, who 19 years earlier had been posted to Draymia's first, and now dead, interplanetary colony, is arrested for "the wanton slaughter of thousands of innocent civilians" (page). This is no plot-spoiler, by the way, since it is already revealed on the teaser blurb on the back of the Del Rey paperback. It seems awfully damned unlikely that the younger Bones, even through inexperience, helped spread that disastrous plague of a generation earlier rather than labored against it, so Kirk and Spock must find the truth where the scrupulously legal and yet here rather closed-minded Draymians will not...even at the risk of the deadly plague itself.
The story is good, though I should comment that I am a tad puzzled by the title. I presume it is a reference to Samuel Taylor Coleridge's "The Rime of the Ancient Mariner," which gives us the notion, known even to those who have never read the nineteenth-century poem, of being cursed by having an albatross--a very large and heavy sea bird, which upon decay after death presumably would not smell so great, either--hung from one's neck. In the poem, of course, it is a fitting punishment for the man who needlessly shot the friendly bird with his crossbow. But here... Well, McCoy of course actually has no sin or crime for which he needs to atone. And unless I missed it somehow, I really don't think the text, whether through authorial narration or through dialogue, gave us any nudging reference. This issue doesn't detract from the plot itself, but...well, it is a bit odd.
"The Practical Joker," whose original script was by Chuck Menville, begins by following up on a crack Spock made at the end of the previous episode, about McCoy during his incarceration for genocide and then the race to find a cure to save the ship's dying crew having been "somewhat derelict" in "the daily dispensing of vitamin supplements" (page 62), about which, after indignation and then a moment's thought, Bones displays "a smile of uncommonly fiendish glee" (page 63)...and suddenly now Spock has dandruff (page 67). Violation of the Hippocratic Oath to do no harm notwithstanding, shortly thereafter, a standard run-in with sneaky Romulans leads to a flight through a standard cloud of "most" (page 75) composition and properties. The Enterprise survives, of course, but then the ship is beset with practical jokes that escalate from corny and gently amusing to potentially deadly...
"How Sharper Than a Serpent's Tooth," whose original script was by Russell Bates and David Wise, is one of those Erich-von-Daniken-esque tales--like, say, "Who Mourns for Adonais?" from the original series and adapted in James Blish's Star Trek 7--in which the myths of Old Earth have their origins in visitations from deep space. As often turns out to be the case, however, no matter how overwhelming a seeming god's power and no matter how perilous his anger, Kirk and Spock can find a chink in the godlike armor, with the Captain asserting, not without compassion, that "we're all grown up now," and that "[i]f we fail or succeed, it has to be--must be--done by our own hands. By our own doing" (page 193). Oh, yes-- And here the quotation of the title is explained, too (page 195).
In any event, Alan Dean Foster's Star Trek Log Six may begin with stories originally from a cartoon show, yet the adaptations are well done and aimed at an adult audience, and for any fan of the starship Enterprise and its historic five-year mission, the book will be a swift and enjoyable 4.5- to 5-star read.
