Fritti Tailchaser is a young ginger tomcat in a world where cats have their own language, culture, and mythology. When his friend and prospective mate Hushpad goes missing, Tailchaser sets out on a quest to discover what distant evil threatens the lives of the Folk. Tailchaser's Song is a generic fantasy questing novel with larger-than-life gods and a feline wrapping--but, unfortunately, Williams knows nothing about cats. Gross inaccuracies and general misconceptions strip away the feline aspect and so destroy this book's only unique aspect. I do not recommend it.
In plot, pacing, and writing style, Tailchaser's Song is unexceptional but not that bad. Williams knows how to write a novel, if not a very good one, and the book follows many common fantasy tropes. Tailchaser is an unassuming small "town" youth who leaves on an ill-advised quest which leads him to a big city, to an enemy city, and up against a scheming powerful antagonist so that good may triumph against evil. Bits of interspersed mythology create a powerful setting, yet this mythology still seem out of place when it enters the plot. Williams paces his book well, and Tailchaser's journey feels realistically long while maintaining interesting variety. Best of all, the book doesn't end as soon as evil is vanquished, identifying Tailchaser is a character in his own right and not just a tool of the story. All in all, the book is aptly- but not well-written: readable, passably skillful, but not memorable.
However, what sets this book apart is also what condemns it. Tailchaser is a cat, and his journey leads him through cat cities and against cat gods. But for all this focus on cats, Williams knows little about them. They speak a "high" language which is almost entirely spoken--but domestic cats don't vocalize among each other. Williams believes that kittens are born without fur, that cats prefer forests, that they live in teeming cities, that they can overdose on catnip. Cats also hunt mice and clean themselves and heckle dogs, but on the whole what Williams gets right are generalities and nothing more. Worse, he sets feral cats as the ideal--a dangerous and false lesson to the reader. Real cats are not the indigenous master species presented in Tailchaser's Song, nor do they hate humans for neutering, nor are housecats somehow inferior. Whatever personal secret it is that cats keep in their own silent, heavy-eyed company, despising M'an, building huge cat cities in forests, and originating from powerful old cat-gods is not it.
The premise of this book probably appeals most to cat fans--but the book itself will be most disappointing to cat fans. On the whole, the book is neither very good nor very bad. Capably written but not particularly skillful, it's a fairly average fantasy novel. The cat characters, on the other hand, could be quite exceptional--but this is not a book in the lines of Watership Down or even the Redwall series. In fact, there are barely any cats here--merely predictable human characters wrapped in cursory fur. With nothing else to endorse the book, I don't recommend Tailchaser's Song. While it is not outright bad, it is disappointing.
(As the writing isn't incredibly awful, I can't be quite so virulently negative about this book as I might like to be while still maintaining some sense of a fair assessment. However: I hated it. I hated it a lot--because if you're so captured by the magic of your first pet cat you should at least pretend to know something of that magic before you write a book about it. Cats don't have gender identities and aren't meant to be feral and, for the love of all that which is good, they do not meow at each other. A basic encyclopedia article offers more truth about the mystical depths of cat nature than there are in the 400 pages of this book. I really, really hated it.)
