Hopeful for those who seek harmony in the world . I wouldn't recommend this to anyone who thinks that religious wars, repression of individual spirits or rape of the earth are good things. Those who seek peace, harmony, celebration of each of us and respect for our earth will find this hopeful
Solution: POS
Why? The overall sentiment of the review is positive as the reviewer mentions positive expressions such as 'hopeful', 'will find this helpful' etc.. Hence, the label is 'POS'.

New input: A typical Star Trek book. . This can't really belong to TOS, as it's not actually that closely related to the original series. Following Spock as he tries to reconcile his human and Vulcan sides as he is posted for the first time to the Enterprise, the book also introduces us to a young Scotty in an entertaining side story. We also meet Captain Pike (who might as well be Kirk from the way he behaves), and the previous doctor, engineer and first officer. The plot goes that an ancient (and missing) Vulcan gem, the largest in existence, has been found on a primitive planet which the Enterprise happens to be visiting. After retrieving it, however, mysterious murders start to happen on the Enterprise, while Pike, on the planet's surface, becomes embroiled in a missing person hunt for two young lovers who could have been kidnapped by mutants. And then love blossoms between Spock and another Vulcan on the ship... the ending rounds everything off nicely. This book isn't really anything special, but it's quite entertaining for a Trek book
Solution:
POS
