The Door into Summer
After Heinlein passed away, Del Rey published a book called Grumbles from the Grave, and I had the great pleasure of working with Virginia Heinlein on gathering photos and other material to accompany the letters and text that made up the book. While at her house, I was introduced to a cat named Pixel.It must not have been this particular feline that inspired the cat in A Door into Summer, but it certainly could have been, and I re-read the book as soon as I could.If you haven't read Henlein, you haven't read science fiction, and if you haven't read this, you haven't read Heinlein. It's the quintessential time travel-paradox story. It's exciting, it's fun, and of course, there's the cat.                                                --Alex Klapwald, Director of Production
