You should definitely know what you're getting yourself into with a title like this. As the cover implies, for this book that means exclusively male on shemale content. The latter may be a somewhat ambiguous (and possibly controversial) term, but the initial Wikipedia definition applies here:
Shemale (also known as she-male) is a term primarily used in sex work to describe a trans woman with male genitalia and female secondary sex characteristics, usually including breasts from breast augmentation or use of hormones.
As for the art, that's a lot harder to pinpoint since it's so subjective. "Good" or "bad" doesn't really apply, but if anything, it's more in line with the classic style you saw in
The Double Secret. I don't think I would've personally sought this out on my only knowing to the content and art style, but much like with The Double Secret, I kinda enjoyed it after giving it a read through. How much
you will enjoy it is going to depend completely on you, but if you're looking for something wholly different from our regular, more mainstream book releases, it's certainly worth your consideration.
