The Night Bookmobile

One night, narrator Alexandra stumbles upon a Winnebago called the Night Bookmobile. Upon entering, she finds that it is filled with every word she's ever read, from books to magazines to the backs of cereal boxes. She spends the rest of the book obsessing over the Bookmobile though she is rarely able to find it.
I found the concept of this book interesting and it was such an easy and quick read that I read it almost immediately upon returning home from the library. The ending was extremely strange and unexpected. I enjoyed the concept because it's a personal fantasy of mine to see all the books I've ever read lined up but I didn't really like how it was executed.
