This months book cover review is The Secret of the Time Vault by Clark Darlton. Book six in Perry Rhodans adventure series.
The Time Vault appears to be a zero gravity dance club complete with disco laser ball and disembodied alien head D.J. By the expression of Perry we can see that mid dance, the music has taken a sour turn.
DJ Disembodied Head is unaware of the rooms dislike to his choice of music. By his expression we can see that he has an overinflated sense of self worth and, like most DJs, is oblivious to the fact that playing a music disc actually requires no musical talent to achieve.
No secret there.
