Description:

"** *Readers will hail the book... the humor is delightful!* **" — [Andre Norton](http://www.goodreads.com/author/show/4766.Andre_Norton "Andre Norton") "*This is a novel that won't go bad on you. Many of science fiction's triumphs, even from as little as ten years ago, are unreadable today; they were shoddily put together, not meant for re-use. But Heinlein is durable. I've read this story twice, so far - once in the* Fantasy and Science Fiction *serialized version, once in hard covers - and expect to read it again, sooner or later, for pleasure. I don't know any higher praise.*" — [Damon Knight](http://www.goodreads.com/author/show/23000.Damon_Knight "Damon Knight") in * [In Search of Wonder](http://www.goodreads.com/book/show/1173067.In_Search_of_Wonder "In Search of Wonder") * Lummox had been the Stuart family pet for years. Though far from cuddly and rather large, it had always been obedient and docile. Except, that is, for the time it had eaten the secondhand Buick . . . But now, all of a sudden and without explanation, Lummox had begun chomping down on a variety of things -- not least, a very mean dog and a cage of virtually indestructible steel. Incredible! John Thomas and Lummox were soon in awfully hot water, and they didn't know how to get out. And neither one really understood just how bad things were -- or how bad the situation could get -- until some space voyagers appeared and turned a far-from-ordinary family problem into an extraordinary confrontation.
