Oh how I love it when the New York Times serves up decidedly different takes on the same book in its daily and weekly pages. Michiko Kakutani delivered a tough but largely positive review of Lorrie Moore’s “A Gate at the Stairs” in Friday’s paper, whereas Jonathan Lethem out and out raves about it in the paper’s Sunday book review section, suggesting that doubters ought to have their head examined.

So which is it? I have an even more mixed take on the book. There was much to love in “A Gate at the Stairs” — narrator Tassie Keltjin is affecting, as is her quirky family — but its weaknesses bugged me long after I finished reading. The plot, tied to fallout from 9/11, begs credulity. And I generally find it annoying when authors withhold key plot information under the guise of character obliviousness or diffidence, as was the case here. Killer closing lines couldn’t quite make up for those deficiencies.

Kakutani notes Moore’s clumsy job orchestrating certain revelations and an unfortunate tendency toward wordplay, but forgives those weaknesses, judging “A Gate at the Stairs” the author’s best book yet.

“If Ms. Moore, who started out as a short-story writer, demonstrates some difficulty here in steering the big plot machinery of a novel, she is able to compensate for this by thoroughly immersing the reader in her characters’ daily existences,” Kakutani writes.
