I found the entire Apprentice Adept series in a used book store a while back, and since I only read 1-3 as a kid, I was super-pumped to get my hands on some craptacular fantasy/sci-fi (Piers Anthony is the MASTER of this particular subsection of the genre).

Wow. WOW. Somehow I'd forgotten the beastiality overtones in the series (which he heavily implies and goes so far as to have other characters talking about the potential for it), along with the standard Anthony racism, sexism, and horrifying compulsion to make fascist dictator states seem cool.

Most eye-bleaching moment is a tie between the scene in Out of Phaze where one of the shape-changing unicorns goes into heat, in girl-form, and so one of the human male characters has to bang the shit out of her day and night for five days, necessitating him creating a spell to give himself more stamina, and the scene in Robot Adept where a smokin' hot vampire chick has to teach a body-swapped girl (who is usually an amoeba) how to go both #1 and #2. Both of these scenes? More than three pages long.

Then again, I just started the final book, so there could be worse things to come.

Someone should have told Anthony that this series needed to end. An excellent idea, which ran to its natural conclusion at the end of the original trilogy. The follow-on books started with some potential, but the steam has run out of them. Book five, Robot Adept , has reached that tipping point. And the repetition has (started to) set in.

The underlying theme is the same: Mach has found himself in Phaze, in Bane's body, and Bane, in turn, has found himself in Proton in Mach's body. Rather than the physical transference of the first trilogy, this continues with the psychic link only instead. To up the game from the previous novel though, this time, an attempted body-switch while embracing their respective partners means that they can now transfer them as well. Cue an almost French-farce type feel to the story as characters rush from one world to the other, having sex with the right partner in the wrong body, or the wrong partner in the right body, or frequently the right partner in the wrong body and a non-human form. Yes at one point, Anthony's adolescent preoccupation with sex means that two characters with shape-changing abilities have to have sex in all three of their forms (at least he doesn't take the next step and write actual bestiality).

Again, the game of Proton is a fixed method for every story resolution – this time a game has to occur half in Proton and half in Phaze (for no reason that's every adequately explained). How the two sides are suddenly able to coordinate when we've been told that Mach/Bane are the only contact though is swept under the carpet (either Bane or Mach even wonders about how that works at one point). And finally, as if the repetition of themes and devices wasn't enough, each time the story switches point-of-view character Anthony feels the need to recap the chapter that we've just read from the new character's point of view. Hang on – all three of us were there in the last chapter. I already know what happened, I just read it!

Somehow, something about the series still hooks me though. I suspect it's more a nostalgia for how much I enjoyed the first trilogy when I also had an adolescent preoccupation with sex, but hopefully there's more to it than that. At least there's only two more to go...

Another sexual sci-fi adventure
14 May 2012

This looks like it is the fifth book in the series, so I guess I am looking at it before the forth book, which isn't a bad thing because as soon as the reviews are done and posted it will not really look all that out of place (with the exception of this little introduction). I did enjoy the first three books, but I really cannot remember reading these books (though I suspect I did). I really did warm to Stile and Sheen (who was a feminine robot that one could have sex with) and wanted to continue their adventures, however by this time Anthony had moved in a new direction.

I do not think these novels are meant for young adults because it is clear that by this time (and it is also very, very clear in Bio of a Space Tyrant) that Piers Anthony is simply obsessed with sex. Okay, granted, he lived through the sexual revolution, but it seems that he had completely missed the point of the revolution. The sexual revolution was all about freeing ourselves of the tyranny of society, and more so freeing women from the tyranny of marriage. By taking sex out of marriage it does destroy the institution of marriage to an extent. My argument (and I know many will disagree with me) is that the institution of marriage had already been destroyed. The reason I say that is because it had become a method to enslave women, and in many ways it is still used as such by certain communities today (and it is that aspect of marriage that repulses me).

Many of the socialist writers have flagged the concept of marriage as being a modern form of slavery. It is not that the male is enslaved but rather the female. That began to change with the women's rights movement in the early 20th century, and then pretty much broke away with the sexual revolution in the 1960s. The question that was asked was 'why do we have to wait for marriage to have sex?' The simple answer was 'because the Bible says so.' Does it? I could quite easily argue that it does not (though I tend to prefer the late John Stott's explanation that it does). However, the response to that was clearly 'I'm not a Christian so why should I listen to the Bible?' This was not a new thing.

Now, I could go on about marriage and sexuality, but I will not and instead turn to Anthony's corruption of the sexual revolution. It is clear from his writings that Anthony holds a very sexist world view. His male characters are so sexually appealing to women that the women fall over themselves to have sex with them. It almost seems as if his characters are some sort of sex-gods. To me it suggests a lot of sexual frustration in Anthony's life, and maybe it is some regret that he did not have as much sex with different people as he would have liked. I have been down that road, and written stories in a similar vein, however I always try to be a little more realistic about it. As for Anthony, I really do question what he is writing here, it is clearly not erotic, but more science-fiction pornography.

Books 4/5 are where the series really breaks down. Because there is no physical link between the frames of Phaze and Proton anymore, Anthony resorts to a mental connection between the offspring of the main characters of the previous three books. The characters play switcheroo across the frames in a Freaky-Friday-esque maneuver, encountering and developing love interests in the opposite frame. Pretty standard cookie-cutter plot with only a few small twists and turns to keep things interesting.

The biggest drawback that I could see is that the story is told from the viewpoint of each of the 4 main characters in turn, but has entirely too much repetition and review to keep my interest. And then just for good measure, one of the characters has a Game in the Proton phase where in the competition of storytelling, she rehashes the entire plot of the story YET AGAIN. By this point in the novel I was just breezing through, waiting to finish the story.

I think this is as far as I've ever gotten in this series - I got my hands on copies of the last few books, but if they're as droll as this one, it's going to be my recommendation for new readers to stop after the previous, 3rd book in the series.

I'm desperately trying to make it through this series, but Piers Anthony is not making it easy. For the most part this is rehashing some of the same stuff from previous books just with the sons of the main characters from the first few books. Even more irritating are the dual world discrepancies similar to the third novel. Suddenly people on both worlds knows everybody's business (rushed writing to push through to more action).

For the most part, the ending is a good, exciting read. Overall, there are some good ideas in this book. There are also some "What was Anthony smoking when he wrote this?" moments.

I stupidly bought several books in this series all at once because until now Piers Anthony has been a reliable author. Here he has apparently decided to bilk his readers for money. This book does not tell a complete story to force the reader into buying the next book in the series. Fortunately the story this book tells is so terrible I am not tempted.

The story is that the good guys and bad guys have come to an impasse so who controls the next set of changes the mirror worlds of Phaze and Proton will be determined by A GAME OF PING PONG!!!!! Stupid beyond belief.

There are other failings, like why the good guys would agree to the competition since there is no reason to believe the bad guys will keep their word if they lose, but do you really need more? In fact this book is so bad that it shades my opinion of other Piers Anthony books I used to like. Now I'm thinking I was just young and naive when I read those and re-reading them will likely be a very disappointing experience.

Spoilers:

This book starts where the cliffhanger of the last book left off, to save their love Mach and Fleta have fled to the bad guys (The adverse adepts.) Mach has promised his assistance in return for a safe haven to be with Fleta but he hopes that Bane will remain free of their clutches between it takes both of them to help the bad guys and Bane remains loyal to his father and the good side over in Science-based Proton--and over there Blue and Sheen have accepted his love match, however Agape is in constant danger from the adverse citizens and it's decided that he must give her up. She has to go back to her home planet so they don't get to be together either.

Things get weirder and more complicated when Mach and Bane meet to switch bodies, but are holding their loves Fleta and Agape and the women switch with them! Now Bane is back in his own body, in his own Frame, and his love is with him, but there are lots of problems with her being there, mainly in that she can no longer be sent off planet to keep her safe because Fleta is now in her body!

The bad guys and the good guys end up coming to an agreement. They will work out a contest between the frames. The two men will compete in a series of challenges. If Bane wins both he and Mach will be free of the bad guys--but they will lose their romances. If Mach wins then Bane will join him in the enemy camp and will help the bad guys to overthrown Blue which could mean destruction of their planet--but they get to keep their ladies.


The book ends with a definite decision, but of course there is no happily ever after in this situation. No matter which side wins they both lose something.

I remember when this book came out and I saw the fantasy cover and thought “what’s this about?” I was in 6th grade and I read some of it in the library while waiting for my parents to pick me up from school. Once it mentioned sex and naked people, I definitely knew it was a grown up kind of book but I kept reading it because, well, unicorns. I got about a third of the way in when it was checked out and I never saw it again. The title stuck with me all these years and after 30+ years I finally looked for it to finish what I left unread. Yay for the 6th grader in me but yuck, what a horrible experience. It was disjointed at best and whiny at worst. This is not a book that the adult me would have ever picked up. It definitely feels like 1980s garbage literature.

The story gets more complicated with this addition. I've always found it tricky when people change bodies or become disembodied. Think of the "Stock's Brain" episode on the old "Star Trek." The romances that the characters regard as all-important probably do more to confuse the story rather than move things along. Taking two points of view during the story and the parts that cover the characters' play in the Game Tournament are, I feel, the best-moving parts.

I don't know why I keep reading the books in this series. The writing is execrable, the plotting moth-eaten, the preoccupation with teen-age sex deplorable. I did enjoy Blue Adept when I first read it years ago, so maybe it's nostalgia. But there is something that still grabs me...."The Game", an elaborate anything-goes tourney, is still fun. And who can resist shape-changing unicorns, trolls, emotional robots and dastardly adepts, oh my. Not a bad read for a hot summer's day with a cool ice tea and some cheese & crackers. Gotta get on to the next one.

Book five, so you gotta read the others first to enjoy or even understand. But this pushes the story right along, and I am off to read the next one.

After their parents forbid their loves Mach and Bane defect.

Mach/Bane are still more likeable than Stile, the "Game" is still a mystery to me, and the citizens/adepts still suck.

The series is really beginning to wear on me. The Phaze dialect suffered severe mutation since the original trilogy. The verb “to be” now has only one form—I be happy that he be taking care of you so you be well. And the word “of” now consists o’ only one letter. Mach and Bane were only introduced in book 4 and they’re already generating progeny. Who are the most advanced four-year-olds in the history of the human race. Sure they’re smart, but the also have completely adult understanding of morals, ethics, the causal relationships between abstract concepts, etc. Now throw in the rapid-fire exchanges of consciousness—I could never keep track of whose mind was in whose body. (These two now: are they romantically involved brains in mismatched bodies, or do the bodies belong together except they have the wrong people in their heads? And which one of them really needs to be in the other frame to avert disaster?)—and mix in the idea that one person’s promise properly commits—without their knowledge or consent—half a dozen other people. Well, I’ll have to see it through to the end, I guess.

Mach, a self-aware humanoid robot of Proton and Bane, son of the Blue Adept of Phaze, have managed to cross the barrier between the scientific world of Proton and the magical world of Phaze. They are doing this by inhabiting each other’s bodies. They are the only two able to do so, and because of this two different factions vie to control them and use their power. They have also fallen in love with females, Fleta the Unicorn of Phaze (with Mach) and Agape, the amoeba from the planet Moeba (with Bane) and are both also in danger of being used to force the two to cooperate.
Much of this book concerns the same events told from the perspectives of all four of the players. The constant back-and-forth, in addition to the confusion of trying to remember which consciousness inhabits which body in which world, makes for a somewhat confusing, but also very repetitive read. It seemed to me, also, there were several plot holes; ways in which the central conflict could have been resolved without further ado. However, ado is what makes a book, and so it goes on. I felt that there was altogether much more sexual activity than was necessary, as well. (Vague Spoiler Alert!) I was also quite disappointed with the ending, and am apprehensive about what will ensue in the next book. I’m sure everything will turn out to be fine, but the ending is not terribly optimistic.

As I read these books I have to wonder, did Anthony ever lose track of his characters? In this chapter of the Apprentice Adept series, Mach and Bane have discovered that their switching places is endangering both the frames of Phaze and Proton. Now the two must decide between their love or the survival of the frames. And... SPOILER ALERT!!! We get an surprise plot twist in the form of Agape and Fleta... exchanging bodies across the frames. Now there are four characters crossing the curtain and all have very important roles to play. This is where, I would (as the author) have trouble keeping track of which character was where. I would be re-reading every page to make sure I was writing the correct person's story. This just shows what wonderful skill Anthony has as a writer. Oh and... he brought the Game back into play. Fleta enters the game as Agape in a magnificent ploy to help the Alien get to safety, out of reach of the Contrary Citizens. And the story spins on, while the excitement builds. I was, mentally, on the edge of my seat for most of this book. I just could not put it down! This book, in my opinion, didn't really have an ending. I felt like I was left hanging when I got to the last page. It's a good thing that I have the next one on hand! Five out of five stars for Robot Adept!

Robot Adept lacks what little charm Out of Phaze has, but it's not nearly as offensive as Unicorn Point. It continues to bank on the stranger-in-paradise concept by this time having the love interests switch - which gives us rather more access to their characters, and they do develop into relatively sympathetic people. Moreso than their partners, certainly. There's only one attempted rape, and it's foiled in a rather satisfying way (raping an amoeba Does Not Work when she can easily reform her abdomen into a fully functional vise.) The book ends with yet another plot-determining set of contests - this mechanism is a little creaky at this point, but it's entertaining enough to read. (Although... another table tennis match? They could use all the games in the universe, but you had to use this one again? Weren't up for any reseach, were you, buddy?)

Definitely the point at which the series begins to decline, but not all that objectionable in itself.

Can I burn my eyes out, please? No? Well then you force me to explain why they need burned out.

This book is book #5 of the whole series and 2nd in this section of it and it sucks. In this book you have to read the same scene from 2 different people each time. It's not even a short little thing, we have to reread the same scene just from the other persons POV. Also I didn't need to read about Agape learning to use the restroom! And as other reviews have said Oh the sex, every time you turned around some was having sex or faking having sex! I would have loved more story line, but no we need to read about using the bathroom and having sex!

In this book, Mach and Bane are still travelling between the parallel worlds, working for the Adverse Adepts and Contrary Citizans rather than their own parents. Neither likes the situation, but with each loving a woman from the opposite frame, they are forced to do as they would rather not.

I quite enjoyed reading this, but felt the series as a whole had rather stalled a bit. The story itself only progresses so far and once again, the Proton Game is used to decide the fate of the world. So, a bit repetitive after reading the other books.

I strongly encourage this be read as the entire series. The last books go in a very different direction than the first few.

At first, this seems a rather typical fantasy type book. Toward the end, well, the comparison to our own world is inevitable and powerful.

Why can't we all just get along?

I'm giving the series a rating of 4. Some of the books in the series are better than others. As a whole, I think it's worthy of a 4.
