1. Quo vadis
2. Tra dezerto kaj praarbaro
3. Libroj de Claude Piron

Of course that they have a lot of books for children. It is just that I am too old to read them anymore.

I have a follow up question. Where do you buy them from? Is there a website that has a list of books according to reading level?

I don't know of a place that has a list of Esperanto books by level. The UEA (uea.org) has an online catalog but if you live in the US, for example, it will be easier to buy from the book store at esperanto-usa.org.

Look at their used book section. You can sometimes get great deals there.

A friendly tip - you might see some great looking books. Many a beginner has heard "Oh, Kroatmilita noktolibro is a great book, I'm going to buy it and read it!" (it is a great book, btw). I recommend against buying such a book as a beginner, however. Beginners read so slowly that even a relatively short book can take an eternity, and as you complete one page, it has taken so long that you have already forgotten what was going on at the beginning of the page. In this situation it's easy to lose the thread and be reading words without having any idea what's going on. I recommend short stories to beginners. It's far easier to understand a story that is only a few pages long from start to finish - you can get an entire story in the same amount of time it would have taken you to read a single chapter of a different book. Sten Johansson writes great stories in Esperanto, and you can find many free examples of his stories online. Most of his stuff is not written for beginners but it is faster to read a short story in "normal" Esperanto than to focus on children's books (which btw are not usually that much easier grammatically).

It is important when learning a language to feel a sense of success while you read - it is discouraging and depressing to spend days and days reading a book, to realize that you are only 10 pages in and you have no idea what is going on in the story.

For a childrens book, I recently read the Esperanto translation of "Winnie the Poo", which I thought was fantastic (and which you can get from the Esperanto-usa book store), it's also nice that it has an Esperanto-english glossary in the back that defines almost all of the words used in the book. There is also an Esperanto translation of Alice In Wonderland (which I haven't read so I can't comment on it's quality), and I'm sure you can find many other children's books, both original and translated.

I'm interested in Esperanto history, so I enjoyed "Paroladoj de Zamenhof". "Esprimo de Sentoj en Esperanto" by Edmond Privat is another good one (if you're interested in reading about esperanto as a language). For a langauge with relatively few speakers, there really is an astonishing amount of literature available in Esperanto, so it just depends on your personal preferences really.

Esperanto-USA has a list of books recommended for beginners:
http://esperanto-usa.org/en/content/recommended-bo...
The first book on that list includes a section that is a set of readings (50 pages or so I think), that are nice because they are at the beginner level, but I didn't find the content of the readings to be particularly interesting.

They also have a list of books for "post-beginners":

Of those, I've only read the first one, and it is quite good, but it's written in English, not Esperanto.
