All across Greater Toronto today, once school lets out, voracious readers aged 10 and up — "and up" here means youngsters well into their 30s — will head straight to their local bookstore.

While this may sound like a grand thing in our digital age, these young consumers will be set on purchasing a particularly dreadful book, one they will take home and briefly shelve beside 12 other similarly sad and miserable books, before they pull it back down and disappear into its pages until called for supper.

The little book that goes on sale today is titled The End (HarperCollins, $16.99). It is also known among awaiting fans as Book the Thirteenth, as in the 13th and final instalment in Lemony Snicket's A Series of Unfortunate Events — which would easily be the most successful Kid Lit franchise of all time, if it weren't for that Harry kid on his flying broom at Hogwart's.

This has made Lemony Snicket a household name, while leaving its actual creator, the San Francisco author Daniel Handler, feeling "bittersweet" at the series' completion — but sounding nothing like that during a phone chat this week from New York, where he was preparing for today's launch with musical collaborator Stephin Merritt and series illustrator Brett Helquist.

According to its fortunate publisher, the series now has 50 million copies in print. A paperback release of the full series, redesigned to mimic those penny novels of yore, is set for May. There are two other books, Lemony Snicket: The Unauthorized Biography and this fall's confection, The Beatrice Letters. Both provide extra clues to the many tantalizing secrets, allusions, sundry hints and broad winks, literary and otherwise, that have made A Series of Unfortunate Events a busy blogosphere guessing game.

There's a 13-song musical CD this week, created by the prolific and eclectic Merritt (of Magnetic Fields fame) titled The Tragic Treasury: Songs from A Series of Unfortunate Events. Plus there's a certain film starring Jim Carrey that also grossed more than $100 million.

All this in little more than seven years, since The Bad Beginning in 1999 brought the three Baudelaire orphans and the evil Count Olaf into a black-humoured world akin to that of Edward Gorey and Roald Dahl, two of Handler's own favourites.

Handler is now filthy rich at 36 but at best a mid-list author for his own three adult novels. A fourth is in the works, to be published as early as next year. It's about pirates, or at least a romantic longing to live the pirate life.

"It is my hope that it will be long enough away so that everyone has forgotten all about A Series of Unfortunate Events, and managed to recuperate and get some of their happiness back before another book drops into their laps," he says.

Alas, his only Canadian event is in Vancouver, but not because he has anything against us. He's rather fond of a country that warmed to the Snicket books much earlier than America.

The fact that the series' editor is Torontonian Susan Rich doesn't hurt — and might explain some of the Canadian place names scattered through the books.

"Canada is so cold and desolate that I think you just really get it," Handler applauds.

Obviously, trading witticisms with Handler is an intimidating proposition. So we invited 14-year-old Leaside High School student Maggie Laidlaw to assist, having met her last year when she waited first in line for hours before Handler's most recent Toronto appearance. But Maggie betrayed us, expressing contempt at our professed hope that Snicket might have fooled us with a happy ending for the Baudelaires in The End.

"I would have to agree with Ms Laidlaw," intoned Handler. "I would think that you are quite foolish ... in addition to forcing young women into the presence of dreadful books."

Indeed, The End ends, as Handler puts it, as "ambiguously" as the series began.

How do you top some 50 million books in print? In Handler's case, you don't retire with your illustrator wife and 3-year-old son. You keep working. There's that next novel to complete, plus all manner of writing for film, the Internet and other projects such as a music video he's directing in Vancouver.

It appears the elusive Lemony Snicket can't slow down either: "The life of a rhetorical analyst is never done."

There's The Composer Is Dead, a kind of Peter and the Wolf piece "for narrator and orchestra" that "Snicket" recorded in July with the San Francisco Symphony Orchestra. Next May will bring another Snicket title. Horseradish: Bitter Truths You Can't Avoid is billed as Snicket snippets taken from "personal papers, conversations at dinner parties and anarchist rallies."

Trust Maggie to tease out the news that more full-blown Snicket novels might be ahead:

"I already find your interest on such topics to be quite unhealthy. But I do admit that Mr. Snicket has expressed interest in some other cases that may have some overlap with the Baudelaires. But I don't think you should read them and so I think you should forget that I ever said that."
