hi ugly bat, and welcome to the forum. it's great you are reading, it's really important to learn about the world and life, and reading is a great way to do that ! and there are plenty of fun things to read, as well.
like people said already, you can get thousands of completely free books right here ; another great site you should look at is feedbooks.com, they also have a huge offer and it is all free as well.
save your money and if you want to you can get a reading device one day ; you don't have to buy an expensive one, like others said, there are many cheaper options like a used cellphone which can read books, or used pda. sometimes you can find those for only about 25$ i hear. if you want suggestions for that, when you're ready, you can start a thread, i'm sure there will be lots of ideas.
in the meantime, enjoy all the free books ! happy reading !
