Great FREE Kobo eReader reads?

Anybody got some good recommendations?

There’s already a current Lets Share Free E-book Recommendations! thread.

Some of the links in that thread are to Kindle editions on Amazon, but most of the free books that are available there can also be found elsewhere, like http://www.gutenberg.org/ or http://manybooks.net/. Just make sure you download the correct version for your e-reader; I think the Kobo uses the ePub format, but I’m willing to be corrected.
