Masters of the Universe • She-Ra, Princess of Power • The Secret of the Sword, Part II - Princess of Power {Read Along Book • Kid Stuff Records & Tapes DBC #298}

Edited Description Taken From An A*z*n Review:  
These two books comprise an exceedingly faithful, if abridged, adaptation of the film, and any evaluation of the story in the books holds equally true for the film. It contributes to the He-Man mythos in meaningful ways, both by introducing Adora/She-Ra and incorporating Hordak and the Horde into the Filmation world (although one has to put from one's mind the fact that they quit making He-Man episodes for the purpose of making She-Ra ones instead).
All the art in these books is taken directly from the film & given that the read-along audio was taken from the original movie soundtrack, this was the next best thing to watching the movie in the days before it was available on home video.
