Nehama Leibovitz z"l died 11 years ago, and this haggada is new.  The cover of the haggada does _not_ credit her with authorship; it says it's a book of studies on the haggada "from the teachings of Nechama Leibovitz," and that it's edited by Yitzhak Reiner and Shmuel Peerless.  I saw it in a bookstore a few days ago, and had the impression that it was really a pastiche of material from Nehama's works on Bible, and that the focus of her inquiries was the biblical text rather than the haggada text.  It was precisely for that reason that I did not buy the book.  Nehama Leibovitz was one of the great Bible teachers of our time, and she was _the_ great teacher of parshanut, but there's an important difference between Nehama explaining what Rashi says about a Torah verse, on the one hand, and Nehama explaining how the Passover Haggada uses that verse.

Has anyone looked more closely at this book, and is my caution merited?
