Hi Gretchen,
I suffered greatly my first few months here until I bought a Kindle. I can’t afford to buy as many books as I read so I use library accounts in the U.S. I have two friends from different areas who have been kind enough to let me use their library accounts and I can get all the books I want for free. Most libraries allow a 2 to 3 week checkout of e-books and they are automatically returned on their due date so you don’t have to worry about late fees.
There are some expat lending libraries or book swaps in the more populated areas but I don’t know what’s available in Canoa. I definitely recommend getting a Kindle and a U.S. library card. Also, there are several websites that send out daily e-mails listing which e-books are free on Amazon each day.
