Just thought I'd mention that I went to the Tantor site to grab a free download of Summer (someone here posted a head's-up, so thanks for that) and wound up on their email list. They have more than 100 downloads available for $6.99, wide range of taste, both contemporary and classic fiction, as well as some non-fiction. Both my brother and I found a bunch of titles we grabbed.
Hope everyone finds something they like--
